What is a compound made up of?
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds.
A molecule consisting of atoms of only one element is therefore not a compound..
What are the 118 elements and their symbols?

What is the difference between a compound and a molecule?
A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. … An example of a molecule is ozone.
Whats is a compound?
A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together. The type of bonds holding elements together in a compound can vary: two common types are covalent bonds and ionic bonds.
What is symbol and formula?
A chemical symbol is a one- or two-letter designation of an element. … Compounds are combinations of two or more elements. A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements.

What do the numbers in compounds mean?
The small number behind each element symbol designates the number of atoms of each element in a chemical formula. … A large number in front of a compound designates how many units there are of that compound.
What is a good example of a compound?
Examples of compounds include table salt or sodium chloride (NaCl, an ionic compound), sucrose (a molecule), nitrogen gas (N2, a covalent molecule), a sample of copper (intermetallic), and water (H2O, a covalent molecule).
What is a compound word examples?
Compound words are formed when two or more words are joined together to create a new word that has an entirely new meaning. For example, “sun” and “flower” are two different words, but when fused together, they form another word, Sunflower. … Consider the words “make up” and “makeup”.
How do you read a compound element?
When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. ” mono-” indicates one, “di-” indicates two, “tri-” is three, “tetra-” is four, “penta-” is five, and “hexa-” is six, “hepta-” is seven, “octo-” is eight, “nona-” is nine, and “deca” is ten.
How do you read chemical symbols?
Chemical Formula A chemical symbol is a one-or two-letter designation of an element. Some examples of chemical symbols are “O” for oxygen, “Zn” for zinc, and “Fe” for iron. The first letter of a symbol is always capitalized. If the symbol contains two letters, the second letter is lower case.
What are 5 examples of compounds?
Examples of Compounds:Water – Formula: H2O = Hydrogen2 + Oxygen. … Hydrogen Peroxide – Formula: H2O2 = Hydrogen2 + Oxygen2 … Salt – Formula: NaCl = Sodium + Chlorine. … Baking Soda – Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3 … Octane – Formula: C8H18 = Carbon8 + Hydrogen18
What does the formula of a compound represent?
A chemical formula tells you the specific elements included in the compound and the number of atoms of each. The letters in a chemical formula are the symbols for the specific elements. … The numbers added as a subscript tell you how many atoms of each element are present.
How do you read a balanced equation?
In general, however, you should follow these steps:Count each type of atom in reactants and products. … Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances. … Repeat steps 1 and 2 until the equation is balanced.
