| Chemical Formula | A group of chemical symbols and numbers that represent the elements and the number of atoms of each element that make up a compound. |
| Compound | A substance made up of atoms of two or more different elements joined by chemical bonds. |
| Conductor | A device designed to transmit electricity, heat, etc. |
| Covalent Bond | A chemical bond that involves sharing a pair of electrons between atoms in a molecule. |
| Ductile | A metal that is able to be drawn (made) into wire. |
| Insulator | A material that does not allow heat or electrons to move through it easily. |
| Ionic Bond | A chemical bond caused by the transfer of electrons from one bonding atom to another that results in oppositely charged ions attracting. |
| Malleable | Easy to shape or bend. |
| Metallic Bond | A chemical bond resulting from the attraction between a positive metal ion and the electrons surrounding it. |
| Mixture | Can be easily broken down into substances. |
| Molecule | The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms held together by chemical forces. |
| Polar Covalent Bond | A covalent bond between atoms in which the electrons are shared unequally. |
| Subscript | A number written slightly below and to the right of a chemical symbol that shows how many atoms of an element are in a compound. |
| Substance | A material that must be broken down chemically. |
| Valence Electrons | The outermost ring of electrons in an atom. Used to determine whether an element is an insulator, conductor or semiconductor. |
