All atoms of an element always have the same number of question 4 options: electrons protons electrons neutrons save

All atoms of an element always have the same number of protons (the positively charged subatomic particle).

Isotopes of the element differ in the mass which means that they differ in the number of the neutrons (which are the subatomic particles having no charge).

At neutral state only will the number of protons be equal to the number of electrons in an atom.

Fake and a real . . . . . ..
