Question

in the formation of compound between two atoma A and B , A loses two electrons and B gains one electron . (a)what is the nature of bond between A and B? (b) suggest the formulae 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.
