| Term | Definition |
| Alloy | Mixture of two ore more metallic elements. |
| Covalent Bond | A chemical bond in which atoms are held together by their mutual attraction for two or more electrons they share. |
| Covalent Compound | A substance such as an element or chemical compound in which atoms are held together by covalent bonds |
| Dipole | A separation of charges that occurs in a chemical bond because of differences in the electronegativities of the bonded atoms |
| Electron-dot structure | a shorthand notation of the shell model of the atom in which valance electrons are shown around an atomic symbol. |
| electronegativity | The ability of an atom to attract a bonding pair of electrons to itself when bonded to another atom. |
| Ion | An atom having a net electrical charge because of either a loss or gain of electrons |
| Ionic bond | A chemical bond in which there an electric force of attraction between two oppositely charged ions |
| Ionic Compound | A chemical compound containing ions |
| Metallic bond | a chemical one in which positively charged metal ions are held together within a fluid of loosely held electrons. |
| Molecule | The fundamental unit of a chemical compound which is a group of atoms held together tightly by covalent bonds |
| Nonbonding pairs | Two paired valence electrons that are not participating in a chemical bond |
| Nonpolar | Said of a chemical bond or molecule that has no dipole. In a non polar bond or molecule, the electrons are distributed evenly |
| Ore | A geologic deposit containing relatively high concentrations of one ore more metal-containing compounds |
| Polar | Said of a chemical bond or molecule that has a dipole. In a polar bond or molecule electrons are congregated to one side. This makes that side slightly negative while the opposite side is slightly more positive |
| Polyatomic Ion | An ironically charged molecule |
| Substituent | An atom or nonbonding pair of electrons surrounding a centrally located atom |
| Valence Electron | the electrons in the outermost shell of an atom |
| Velence Shell | The outermost occupied shell of an atom |
| Valence Shell electron-pair repulsion | A model, that explains molecular geometries in terms of electron pairs striving to be as far apart from one another as possible |
