Chemical Compounds
Compounds, Bonds, Formulas, Equation, & Law of Conservation of Matter
Definition | Terms |
---|---|
This shows how many of each kind of atom is present in a compound and is written to the lower right of the element symbol. | subscript |
Are composed “made up” of more than one “different” atom that is chemically bonded. | compound |
The process in which one or more substances are converted/changed to one or more different substances. | chemical reaction |
A force of attraction that holds atoms together as a result of the rearrangement of electrons between them. | chemical bond |
Are the new substance(s) that is formed in a chemical reaction. Are found on the right side of the arrow. | product |
Molecule that is made up of all the same kind/type of atom. These molecules are two of the same atom or element. | diatomic molecule |
Bonds, that are formed when metals react with nonmetals. The electrons are transferred/moved from the metal to the nonmetal atom/element | ionic bonds |
The number that comes before the chemical formula, that indicates the number of particles or molecules that participate in the chemical reaction. | coefficient |
States that during a chemical reaction, matter is not created or destroyed. Also, the atoms present in the reactants are also present in the product. | law of conservation of matter |
A shorthand way to use chemical symbols and numbers to represent a substance | chemical formula |
Are substances that you start with and are broken apart or combined in a chemical reaction. Are found on the left side of the arrow. | reactant |
Bonds that are formed between two nonmetals and the electrons are shared. | covalent bond |
Is used to represent a chemical reaction and it contains/shows the chemical name or the chemical formulas of all the substances involved in the reaction. | chemical equation |
Are made up of one kind of atom. All elements have a unique symbol | element |
