Answer:
when atom is neutral it has a no charge, looses electron has positive charge, gains electron gets negative charge
Step-by-step explanation:
protons have positive charges (+)
electrons have negative charges (-)
when an atom is neutral is means no additional electron is lost or gain
When an atom has a neutral charge it has neither too much or too little electrons since it has not gained or lost any thus the zero charge ( no charge)
When an atom loses an electron since its losing an electron that has a negative charge it becomes a bit more positive so thus the positive charge
When the atom gains an electron it gains a bit more negativity then it had so its going to have a negative charge
