If this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be

No charge (0)

Explanation:

The atom has a proton of 22 and electron number of 19. This means the element has lost 3 electrons. Therefore, the net charge is +3.

So, if this atom gains 3 more electrons, the net charge would be zero (neutral).

The total number of electron would now be 22 which is the same as the proton number.

This implies the atom is now in an unreacted state or ground state.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
