Detailed explanation-1: -The aluminum ion has 10 electrons and 13 protons, so it has lost three electrons, and has a charge of 3+ .
Detailed explanation-2: -The atomic number of aluminum is 13. This suggests that the number of electrons present in the Al3+ ion is equal to (13-3 =10) electrons.
Detailed explanation-3: -When an aluminum atom becomes an ion, it drops three electrons. Since there are only 10 electrons, their value is subtracted from the number of protons, and the difference is a positive three. Therefore, an ion of aluminum has a positive charge of three, shown as 3+.
Detailed explanation-4: -The number of protons and neutrons in is 13 and 14. Al have mass number 27. It have electron 13 so number of protons will also 13.
