Question

Why non metals gain electrons to form negative ions ?

Answer 1

When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. Most nonmetals become anions when they make ionic compounds. A neutral chlorine atom has seven electrons in its outermost shell.

Answer 2

Answer:

it forms when atoms of a metallic element give up electrons to atoms of a non metallic element. ionic bonds form only between metals and nonmetals. that's because metals "want" to gain electrons..... energy is released when an atom gains valence electrons and form a negative ion.
