consist of a metal and nonmetal. (ionic Bonds)
ions
Cation: named by adding the word ion to the name of the element
Anion: named by changing the ending of the element’s name to –ide.
empirical formula
simplest formula of a compound
polyatomic molecules
contain more than two atoms
molecular compounds
consist of two nonmetals (covalent bonds)

molecular formula
shows the exact number of atoms of
each element in a molecule
Diatomic molecules

organic compounds
contain carbon and hydrogen, sometimes in combination with other
atoms
molecular compounds
most positive element named first.
greek prefixes for the number of each element present

ions (H+) when dissolved in water
ionic compounds
Fixed charged metals add -ide to the nonmetal
variable charge use roman numerals to indicate the charge on the metal
lattice
