• Name the cation
• Put cation charge in () using roman numerals after cation name
• Change the ending of the anion name to "ide"
• Never change the name of a polyatomic ion
• Use prefixes in front of element name to signify quantity in molecule
• Do not use mono on first element, use it everywhere else
• Change last element in compound to end in "­ide"

• Count all valence electrons
• Add or subtract from total if the molecule is charged
• Put least electronegative element in center
• Single bond elements together from center out
• Complete octets on outer elements (any leftovers will go on center element)
• Anion will have gained electrons
