Study Notes

Ionic Compounds Overview

Sodium nitrate is represented by the formula NaNO3.
The oxygen ion in Cr2O3 has a charge of -2.

Ionic Compound Formation

Lithium is likely to form an ionic compound with chlorine.
Calcium phosphate is denoted by the formula Ca3(PO4)2.
A cation carries a positive charge, formed when an atom or group of atoms loses electrons.

Transition Metals and Ions

The cation Fe3+ forms when iron loses three electrons.
Metals in groups 1, 2, and 3 typically lose electrons to form cations.
For transition metals with multiple oxidation states, the charge is indicated by a Roman numeral in their name.

Chemical Formulas and Polyatomic Ions

The number of each element in an ionic compound is shown by subscripts.
