Ionic Compounds Nomenclature and Formulas

Ga2(SO4)3 is known as gallium(III) sulfate, indicating the oxidation state of gallium.
Ammonium sulfate has the chemical formula (NH4)2SO4, showcasing the ammonium ion's presence.
Roman numerals are required in the names of ionic compounds when the cation is a transition metal, indicating its charge.
Ammonium carbonate's chemical formula is (NH4)2CO3, highlighting its ammonium ion composition.
AlBr3 is called aluminum bromide, which illustrates aluminum's +3 charge balancing with bromide's -1 charge.
Nickel (III) oxide has the chemical formula Ni2O3, reflecting nickel's +3 charge in the compound.
Cs2S is referred to as cesium sulfide, with cesium contributing a +1 charge and sulfide a -2 charge.
The compound consisting of Ca^2+ and Br^- ions has the formula CaBr2, indicating calcium's +2 charge balanced by two bromide ions.
To neutralize an ion with a -2 charge, two ions with a +1 charge are needed, demonstrating charge balancing.
The ratio of Sr^2+ ions to Br^- ions in a neutral compound is 1:2, necessary for electrical neutrality.
Cu(NO3)2 is named copper(II) nitrate, reflecting copper's +2 oxidation state in the ionic compound.
One potassium ion bonds with one chloride ion to create neutral potassium chloride, which follows the +1 and -1 charge balance.
The periodic table predicts stable ionic compound formulas, as metals in Group 2 consistently form cations with a +2 charge.
LiI is known as lithium iodide, which highlights the direct bond between lithium’s +1 charge and iodine’s -1 charge.
