15. In a neutral atom *

1.The number of neutrons and electrons are equal.
2.The proton count can be different.
3.The number of protons and neutrons are equal. The electron count can be different.
4.The number of protons and electrons are equal. The neutron count can be different.

Protons have a positive charge, neutrons have no change, and electrons have a negative charge. So the number of protons and electrons must be equal in a neutral atom. The number of neutrons in itself wouldn’t affect the atom’s overall charge.

Thus, the fourth statement would be the correct one.
