Scandium forms the ion Sc3+. How many bromite ions could bind with Sc3t, and what would be the chemical formula?
ser-zykov [4K]

Answer:  3 bromite ions will bind with Sc^{3+} and the chemical formula will be Sc(BrO_2)_3.

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 Sc^{3+} cation and bromite is an anion with oxidation state of -1 called as BrO_2^-. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Sc(BrO_2)_3.

Thus 3 bromite ions will bind with Sc^{3+} and the chemical formula will be Sc(BrO_2)_3.
