Question

Elements Q and S react together to form an ionic compound. Can Q and S both be metals? Justify your answer.

• A. Both Q and S can be metals.
• B. Both Q and S be non-metals
• C. From Q and S, one should be metal and other should be non-metal
• D. None of the given options is correct

Answer 1

The correct option is C

From Q and S, one should be metal and other should be non-metal

Both Q and S cannot be metals. It is because in the formation of an electrovalent compound, one element accept electrons and the other donate electrons.Ionic compounds are formed between metals and non-metals. The metals have a tendency to lose their valence electrons. So, they combine with the non-metals which have a tendency to gain an electron(s) and form ionic bonds.
