Answer :
if an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.
hope this helps
Question should be corrected
- If the number of protons equal the no of electrons the charge of atom is?
Answer:-
See
- protons have +ve charge
- electrons have -ve charge
If both are equal then
- Net charge is zero
Here the given's question answer must be electron or its wrong
