Answer: 3 bromite ions will bind with
and the chemical formula will be
.
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here scandium is having an oxidation state of +3 called as
cation and bromite is an anion with oxidation state of -1 called as
. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
.
Thus 3 bromite ions will bind with
and the chemical formula will be
.
