Consider the ionic compound that is the combination of the chromium (iii) and hydroxide ions. how many chromium atoms would be present in this compound?

An ionic compound forms when a metal bonds with a non-metallic element. Metals usually form the cation and non-metal anions. Chromium has an oxidation number of +3 in the compound and charge on hydroxide ion is -1.

Cation here is

Anion is the hydroxide ion

So the formula of the compound will be: . The compound has one chromium atom and two hydroxide ions.

Therefore, there will be one Chromium atom per each chromium hydroxide compound.
