An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.
1. Definition (n.) most important point or piece of something. Examples The key element in a White Russian is vodka. Take "key-element" Quiz.
A literary element, or narrative element, or element of literature is a constituent of all works of narrative fiction—a necessary feature of verbal storytelling that can be found in any written or spoken narrative.
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Elements that compose the compound are chemically combined. Elements contain only one type of atom.
Elements cannot be broken down into a simpler substance. Likewise, one element cannot be chemically converted into a different element. Chemical elements are the simplest of substances.
Literary element. For example, plot, theme, character and tone are literary elements, whereas figurative language, irony, or foreshadowing would be considered literary techniques.
Everything in nature is made up of five basic elements: earth, water, fire, air, and space.
- Word order. Word order is the most important element of what is known as syntax.
- Punctuation. Punctuation is another main element of syntax.
- 3 Tense and aspect. Tense and aspect are the most import parameters applying to verbs; and verbs are fundamental to all statements.
- 4 Use of determiners.
- 5 Use of connectors.
A complete sentence must have, at minimum, three things: a subject, verb, and an object. The subject is typically a noun or a pronoun. And, if there's a subject, there's bound to be a verb because all verbs need a subject.

- Capital Letter. The first word of a complete sentence must start with _
- Subject. _ is who or what the sentence is about.
- Predicut. the _ of a complete sentence is the action or what is going on in the senence.
- Complete Thought. the _ is the main idea or logical conclusion.
- Terminal Punctuation.
Students commonly make three kinds of sentence structure errors: fragments, run-ons, and comma splices. 1) Fragments: Fragments are incomplete sentences. Very often, they consist of a subject without the predicate. Example: The child who has a rash.
Definitions of Key Grammar Concepts
- Parts of Speech. In English grammar, the eight major parts of speech are noun, pronoun, adjective, verb, adverb, preposition, conjunction, and interjection.
- Nouns. The easy way to remember nouns is that they refer to people, places, or things.
- Pronouns.
- Adjectives.
- Verbs.
- Prepositions.
- Conjunctions.
- Interjections.
A complete sentence has three characteristics:
- First, it begins with a capital letter.
- In addition, it includes an end mark—either a period [ . ], question mark [ ? ], or exclamation point [ ! ].
- Most importantly, the complete sentence must contain at least one main clause.
The subject and predicate make up the two basic structural parts of any complete sentence. In addition, there are other elements, contained within the subject or predicate, that add meaning or detail. These elements include the direct object, indirect object, and subject complement.
The basic parts of a sentence are the subject, the verb, and (often, but not always) the object. The subject is usually a noun — a word that names a person, place, or thing. The verb (or predicate) usually follows the subject and identifies an action or a state of being.
A complete sentence must have, at minimum, three things: a subject, verb, and an object. The subject is typically a noun or a pronoun. And, if there's a subject, there's bound to be a verb because all verbs need a subject. Finally, the object of a sentence is the thing that's being acted upon by the subject.
There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals. You'll find more specific groups, like transition metals, rare earths, alkali metals, alkaline earth, halogens, and noble gasses.
An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is. Currently, scientists know of 118 different elements.
All of these 118 elements on the periodic table have chemical symbols represented by the first letter or two of the name of the element. If the chemical symbol has two letters the first letter is always capitalized and the second letter is written in lowercase.
An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is. These different versions of hydrogen are called isotopes.

In some traditional sense, you could consider water an element, but it doesn't qualify as an element according to the scientific definition—an element is a substance consisting of only one type of atom. Water consists of two types of atoms: hydrogen and oxygen.
The quick answer is: Diamond is a pure element, carbon; gold is a pure element, gold; and rust is a compound, Iron Oxide, of iron and Oxygen. Diamond is pure elemental carbon, compressed to its crystal form, under extreme heat and pressure deep within the Earth. The symbol for carbon is C.
The Eight Most Abundant Elements in the Earth's Crust
- Elements and Compounds.
- Oxygen: Most Abundant Element in Earth's Crust.
- Silicon: Second-Most Abundant Element in Earth's Crust.
- Aluminum: Most Abundant Post-Transition Metal.
- Iron: Transitional Metal.
- Calcium: Most Abundant Alkaline Earth Metal in Earth's Crust.
All isotopes of a particular element have the same number of protons, but have a different number of neutrons. If you change the number of neutrons an atom has, you make an isotope of that element. All known elements are arranged on a chart called the Periodic Table of Elements.
Examples of elements include oxygen, hydrogen, sodium, chlorine, lead, iron. Examples of compounds include water ( or hydrogen oxide ) H2O; and Sodium Chloride, NaCl. H is the symbol for hydrogen; the number 2 as used here means there are 2 atoms of the element hydrogen in every molecule of the compound water.
An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. Currently, scientists know of 118 different elements. Some, like gold, silver, copper and carbon, have been known for thousands of years.
