Question

In the formation of compound between two atoms A and B, A loses two electrons
and B gains one electron.
(0) What is the nature of bond between A and B?
(ii) Suggest the formula of the compound formed between A and B​

Answer 1

Answer:

B gains an electron, so it is a non metal and forms negatively charged ion. Now, a bond between a metal and non metal is always ionic. I) So nature of bond is ionic or electrovalent. ii) Since A loses 2 electrons, its valency is +2 and valency of B is -1 since it gains one electron.
