Ionic Compounds Nomenclature Quiz

What is the name of the ionic compound AlBr3?

When is a roman numeral most likely needed in the name of an ionic compound?

What is the name of the ionic compound Cs2S?

What is the ratio of ions needed to produce neutral potassium chloride?

What is the ratio of sodium ions to bromide ions in neutral sodium bromide?

How does the periodic table help in predicting the formula of a stable ionic compound?

How many ions that have a +1 charge will bond with an ion that has a -2 charge?

What is the chemical formula for nickel (III) oxide?

What name should be used for the ionic compound Ga2(SO4)3?

What is the chemical formula for ammonium carbonate?

AlBr3 is named aluminum bromide.
Roman numerals are required when naming ionic compounds with transition metal cations.

Cs2S should not be referred to as dicesium sulfide; the correct naming does not utilize prefixes.
The neutral ratio for potassium chloride is incorrect if stated as two potassium ions to one chloride ion.
In sodium bromide, the ratio of sodium ions to bromide ions for neutrality is 1:1.

The periodic table aids in predicting ionic compound formulas; statement regarding Group 1 metals having a -1 charge is misleading.
An ion with a -2 charge will bond with two ions that each have a +1 charge, and the notion that three ions will bond is incorrect.

Nickel (III) oxide has the chemical formula Ni2O3.
Ga2(SO4)3 should not be referred to as gallium(III) sulfide; the correct naming requires attention to polyatomic ions.
Ammonium carbonate has a formula less commonly represented as NH4(CO3)2, emphasizing the correct structure.
