Answer:
A binary ionic compound contains an ion that is a metal (cation) and an ion that is a nonmetal (anion). column of the periodic table (IA) will have a 1+ charge. ▶ (2) Metals in the second column (2A) will have a 2+ charge. Example: Magnesium ion is written Mg2+; the calcium ion is written Ca2+
Most cations and anions can combine to form neutral, solid compounds that are usually known as salts. The net charge of an ionic compound must be zero. Therefore, the number of cations and anions in an ionic compound must be balanced to make an electrically neutral molecule.
