Answer:
If the atom is neutral, then the number of protons(atomic number) equals the number of electrons. If the atom is an ion and has a charge, then that changes. If the charge is negative(ex. 1-), then you add that number to the number of protons to get the number of electrons. If the charge is positive, then you subtract(ex 1+) that number from the number of protons to get the number of electrons
