Sodium phosphate has the formula Na3PO4, consisting of sodium cations and phosphate anions.
Aluminum acetate's chemical formula is Al(C2H3O2)3, containing aluminum cations and acetate anions.
Aluminum oxide is represented as Al2O3, with aluminum in a 3+ state.
Calcium nitride is denoted by the formula Ca3N2, reflecting calcium's 2+ charge.

Magnesium chloride requires two chloride ions to balance magnesium's 2+ charge.
Ionic compounds typically exist as solids at room temperature and possess high melting and boiling points.
They adopt a crystal structure in solid form, contributing to their hardness and brittleness.
While ionic compounds do not conduct electricity as solids, they readily do so when dissolved in water.

Ionic compounds consist of metal cations and non-metal anions held together by ionic bonds.
Polyatomic ions are groups of bonded atoms acting as a single ion, crucial for the formation of ionic compounds.
Multivalent ions refer to metal ions capable of exhibiting multiple charges in different ionic compounds.
