Question

Name the kind of valency belonging to non-metals. Give proper reasons.

Answer 1

• Non-metals have four to seven electrons in their outermost shell due to which they can easily accept electrons from other elements to attain the stable octet configuration.
• When non-metals gain electrons, the number of protons becomes less than the number of electrons, due to which the atom becomes negatively charged.
• Hence, non-metals possess electronegative valency.
