Answer:
Atoms with the same number of protons but with different electrical charges are different ions.
Explanation:
Ions are defined as those atoms or molecules which carry charge. The charge can either be positive (cation) or negative (anion).
As we know an atom is a neutral specie. It contains same number of protons and electrons. Therefore, when the number of electrons are either removed or added they convert the atom into an ion.
Example:
Magnesium have 12 protons and 12 electrons in its neutral state. When one electron is removed from Mg it is converted into Mg⁺. And when two electrons are removed it is converted into Mg⁺⁺. Hence, Mg has same number of protons but different charges in different ions (i.e. Mg⁺ and Mg⁺⁺).
