Answer 2

Atoms contain neutrons, electrons & protons. In a neutral atom number of electron is equal to number of proton. Since the charge on electron is -1 and that of proton is 1. Atoms are able to be neutral.

Answer 3

Thank you very much.

Answer 4

2) When an atom looses electron, number of electrons decreases in comparison to protons. Since the protons have positive charge, Atom becomes positive ion.
