Question

the atom acquires a net positive charge when it losses a negative charged particle explain​

Answer 1

Explanation:

An electron has an electric charge of -1. A proton has a positive charge of +1.

Taking the simplest case, a hydrogen atom (one electron, one proton) has a nucleus with a charge of +1 (due to the one proton) and an electron orbital with charge -1 (due to the one electron). Together, those charges cancel out, and the net electric charge of the atom is zero (that is called being electrically neutral).
