Ionic Nomenclature

Ionic nomenclature is the system used to name ionic compounds, which consist of cations (positively charged ions) and anions (negatively charged ions).

The charge of magnesium in magnesium sulfate is +2.

The formula for sodium oxide is Na2O.

To determine the formula of an ionic compound, balance the total positive charge from cations with the total negative charge from anions.

The name of the compound with the formula Cr(NO2)3 is chromium III nitrite.

The correct name for Cu2CO3 is copper I carbonate.

The charge of aluminum in AlCl3 is +3.

The name of the anion in magnesium sulfate is sulfate (SO4^2-).

The formula for combining Al3+ and Cl- ions is AlCl3.

Copper I (Cu+) has a +1 charge, while copper II (Cu2+) has a +2 charge.
