Question

Comment: “Non-metals are electronegative elements.”

Answer 1

1. Definition of non-metals: The elements which form negative ions by gaining or accepting electrons are called non-metals.
2. Non-metals are called electronegative elements because they tend to gain electrons and form an anion(-ve ion). They have an affinity towards electrons.
3. The negatively charged electron converts it into an electronegative element.
4. For example, Chlorine(Cl) has $7$ electrons in its outer shell, and thus it can gain $1$ electron to be stable. For this, this is an electronegative non-metal.
