The following semicolon rules are highly likely to appear: Replacing a Period (Rule 1a): A semicolon can replace a period to narrow the gap between two closely linked sentences. Example: Call me tomorrow; you can give me an answer then. Before Introductory Words (Rule 2): Use a semicolon before words like namely, however, therefore, for example when they introduce a complete sentence. Example: Bring any two items; however, sleeping bags and tents are in short supply. Series with Commas (Rule 3): Use a semicolon to separate units of a series when one or more units contain commas. Example: The conference has people who have come from Moscow, Idaho; Springfield, California; Alamo, Tennessee; and other places as well. Independent Clauses with Connectors (Rule 4): Use a semicolon between independent clauses joined by connectors like and, but, or when one or more commas appear in the first clause. Example: When I finish here, and I will soon, I'll be glad to help you; and that is a promise I will keep. No Capitalization After Semicolon (Rule 5): Do not capitalize ordinary words after a semicolon. Example: I am here; you are over there.
It's no accident that a semicolon (;) is a period atop a comma. Like commas, semicolons indicate an audible pause—slightly longer than a comma's, but short of a period's full stop. Semicolons have other functions, too. But first, a caveat: avoid the common mistake of using a semicolon to replace a colon. Incorrect: I have one goal; to find her. Correct: I have one goal: to find her. A semicolon can replace a period if the writer wishes to narrow the gap between two closely linked sentences. Examples: Call me tomorrow; you can give me an answer then. We have paid our dues; we expect all the privileges listed in the contract. Avoid a semicolon when a dependent clause comes before an independent clause. Incorrect: Although they tried; they failed. Correct: Although they tried, they failed. Use a semicolon before words like namely, however, therefore, that is, for example, when they introduce a complete sentence. Example: Bring any two items; however, sleeping bags and tents are in short supply. Use a semicolon to separate units of a series when one or more of the units contain commas. Correct: The conference has people who have come from Moscow, Idaho; Springfield, California; Alamo, Tennessee; and other places as well. A semicolon may be used between independent clauses joined by a connector when one or more commas appear in the first clause. Example: When I finish here, and I will soon, I'll be glad to help you; and that is a promise I will keep. Do not capitalize ordinary words after a semicolon. Incorrect: I am here; You are over there. Correct: I am here; you are over there.
When studying for your proofreading test, it's essential to remember several key comma rules. Use commas to separate words and word groups in a simple series of three or more items. For example, "My estate goes to my husband, son, daughter-in-law, and nephew." Use a comma to separate two adjectives when the order of the adjectives is interchangeable. For instance, "He is a strong, healthy man." Use a comma to separate independent clauses joined by conjunctions like and, or, but. For example, "He walked all the way home, and he shut the door." Use commas to set off nonessential words, clauses, and phrases. For instance, "Jill, who is my sister, shut the door." Use commas after introductory words or phrases. For example, "Why, I can't believe this!" and "Having finally arrived in town, we went shopping." Use commas to set off the name, nickname, term of endearment, or title of a person directly addressed. For example, "Will you, Aisha, do that assignment for me?" Use a comma to separate the day of the month from the year, and always put one after the year. For example, "It was in the Sun's June 5, 2019, edition." Use a comma to separate a city from its state, and remember to put one after the state. For example, "I'm from the Akron, Ohio, area." Use commas to introduce or interrupt direct quotations. For example, He said, "I don't care." Focusing on these rules will help you prepare effectively for the proofreading test.

When I visited New York City, I was amazed by the hustle and bustle of the streets. I saw tall, gleaming skyscrapers, and vibrant, busy markets. My friends, John, Sarah, and Emily, joined me on this adventure. We walked through Central Park, and we marveled at the beautiful, serene landscape. Later, we visited the Metropolitan Museum of Art, which is known for its vast collection of art. "This place is incredible," said Sarah. In the evening, we enjoyed a delicious meal at an Italian restaurant. "I can't believe how much we’ve done today," I said. Exhausted but happy, we returned to our hotel, ready for another exciting day.
Traveling opens up new horizons, offering experiences that enrich our lives. Whether you prefer mountains or beaches, each destination has its unique charm. Typing accurately is akin to packing efficiently for a trip. Have you ever mixed up “your” and “you’re”? “Your” shows possession, while “you’re” is a contraction for “you are.” Such mistakes are easy to make but simple to correct with practice. Use all punctuation marks, including colons and semicolons, correctly. Explore the world, and don’t forget to document your adventures through typing!
Healthy eating habits are crucial for maintaining overall well-being. Fruits and vegetables provide essential vitamins and minerals. Did you know that spelling “definitely” incorrectly is a common mistake? Remember, it’s “definitely,” not “definitely.” Punctuation also plays a vital role in clear communication. For example, the Oxford comma can clarify a list: apples, oranges, and bananas. Pay attention to these details when typing. Proper nutrition fuels the brain, aiding in cognitive functions. Keep typing, and keep learning!

The internet is a vast repository of knowledge, offering endless opportunities to learn and grow. Typing proficiently allows you to navigate this digital world with ease. Do you know the difference between “affect” and “effect”? “Affect” is usually a verb, while “effect” is typically a noun. Being mindful of such details improves your writing. Have you ever tried typing without looking at the keyboard? It’s a skill worth mastering. The more you practice, the more natural it becomes. Aim for precision, not just speed!
A journey of a thousand miles begins with a single step. This famous proverb highlights the importance of starting small. When typing, each letter is a step towards completing your goal. Quoting famous authors can be a good exercise. “The only limit to our realization of tomorrow is our doubts of today,” said Franklin D. Roosevelt. Typing quotes can enhance both speed and comprehension. Make sure to use proper capitalization and punctuation. Practicing regularly helps in minimizing errors. Keep going, and success will follow!
Technology has revolutionized the way we live, work, and communicate. From smartphones to smart homes, the digital age is here to stay. Typing skills are now more important than ever. Are you ready to adapt? Every keystroke counts, so accuracy is paramount. People often confuse “its” and “it’s,” but remember, “it’s” is a contraction for “it is.” Furthermore, don’t forget the apostrophe in contractions like “don’t” and “can’t.” Mastery of the keyboard is a valuable asset in today’s world. Keep practicing, and you’ll see improvement!
Typing efficiently and accurately requires practice, perseverance, and patience. It’s crucial to balance speed with precision. The quick brown fox jumps over the lazy dog. Jack quietly faxed a large zigzag-shaped quilt to the museum. How many vowels are in the sentence? Are you sure it’s enough? Don’t forget to check punctuation: commas, periods, exclamation marks, and question marks! Did you notice the semicolon; it’s often overlooked? Complex sentences, like these, can be tricky to type swiftly. Additionally, correct usage of “they’re,” “their,” and “there” is essential. Remember: typing isn’t just about speed, but also about correctness. Practice makes perfect, so keep typing!

A proton is a stable subatomic particle, symbol p, H+, or 1 [H]^+ with a positive electric charge of +1 e (elementary charge). Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the proton–electron mass ratio). Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). One or more protons are present in the nucleus of every atom. They provide the attractive electrostatic central force that binds the atomic electrons. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number (represented by the symbol Z). Since each element has a unique number of protons, each element has its own unique atomic number, which determines the number of atomic electrons and consequently the chemical characteristics of the element.
The word proton is Greek for "first", and this name was given to the hydrogen nucleus by Ernest Rutherford in 1920. In previous years, Rutherford had discovered that the hydrogen nucleus (known to be the lightest nucleus) could be extracted from the nuclei of nitrogen by atomic collisions. Protons were therefore a candidate to be a fundamental or elementary particle, and hence a building block of nitrogen and all other heavier atomic nuclei.
Although protons were originally considered to be elementary particles, in the modern Standard Model of particle physics, protons are now known to be composite particles, containing three valence quarks, and together with neutrons are now classified as hadrons. Protons are composed of two up quarks of charge 2/3 e and one down quark of charge – 1/3 e. The rest masses of quarks contribute only about 1% of a proton's mass. The remainder of a proton's mass is due to quantum chromodynamics binding energy, which includes the kinetic energy of the quarks and the energy of the gluon fields that bind the quarks together. Because protons are not fundamental particles, they possess a measurable size; the root mean square charge radius of a proton is about 0.84 - 0.87 fm (1 fm = 10 - 15m). In 2019, two different studies, using different techniques, found this radius to be 0.833 fm, with an uncertainty of more or less 0.010 fm.
Free protons occur occasionally on Earth: thunderstorms can produce protons with energies of up to several tens of MeV. At sufficiently low temperatures and kinetic energies, free protons will bind to electrons. However, the character of such bound protons does not change, and they remain protons. A fast proton moving through matter will slow by interactions with electrons and nuclei, until it is captured by the electron cloud of an atom. The result is a protonated atom, which is a chemical compound of hydrogen. In a vacuum, when free electrons are present, a sufficiently slow proton may pick up a single free electron, becoming a neutral hydrogen atom, which is chemically a free radical. Such "free hydrogen atoms" tend to react chemically with many other types of atoms at sufficiently low energies. When free hydrogen atoms react with each other, they form neutral hydrogen molecules [H2], which are the most common molecular component of molecular clouds in interstellar space. Free protons are routinely used for accelerators for proton therapy or various particle physics experiments, with the most powerful example being the Large Hadron Collider.
The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period. As early as 1815, William Prout proposed that all atoms are composed of hydrogen atoms (which he called "protyles").
