|---|
| anion | any atom or group of atoms that has a negative charge |
| law of multiple proportions | Whenever two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers |
| base | ionic compound that produces hydroxide ions when dissolved in water |
| ionic compounds | compounds composed of metal cations and nonmetal anions |
| binary compound | composed of two elements and can be either ionic or molecular |
| monatomic ion | an ion consisting of a single atom with a positive or negative charge |
| cation | any atom or group of atoms that has a positive charge |
| polyatomic ion | a tightly bound group of atoms that behaves as a unit and carries a charge |
| acids | compounds that contain one or more hydrogen atoms and produce hydrogen ions in solution |
| law of definite proportions | In samples of any chemical compound, the masses of the elements are always in the same proportions any atom or group of atoms that has a negative charge |
| naming binary ionic compounds | place cation name first followed by the anion name |
| naming polyatomic containing ionic compounds | place name of polyatomicor monatomic cation first followed by polyatomic or monatomic anion |
| naming binary molecular compounds | use prefixes to tell how many atoms of an element are present in each molecule of the compound |
| mono- | prefix meaning 1 atom is present in a binary molecular compound |
| di- | prefix meaning 2 atoms are present in a binary molecular compound |
| tri- | prefix meaning 3 atoms are present in a binary molecular compound |
| tetra- | prefix meaning 4 atoms are present in a binary molecular compound |
| penta- | prefix meaning 5 atoms are present in a binary molecular compound |
| hexa- | prefix meaning 6 atoms are present in a binary molecular compound |
| hepta- | prefix meaning 7 atoms are present in a binary molecular compound |
| octa- | prefix meaning 8 atoms are present in a binary molecular compound |
| nona- | prefix meaning 9 atoms are present in a binary molecular compound |
| deca- | prefix meaning 10 atoms are present in a binary molecular compound |
