→Ions can be written like Ca⁺⁺ or Ca⁺² or Ca²⁺
→Transition metals use Roman numerals to designate the specific charge of the ion
→3 elements in the transition section are exceptions They are zinc, silver, and cadmium
→Only 3 metals outside of the transition section use Roman numerals. They are tin, lead, and bismuth.
→The only metalloid that uses Roman numerals is antimony.
→Negative monatomic ions use the family number to determine charge: V=-3, VI=-2, VII=-1
Ions to be memorized.
I never want to write the word ion again.
