The number of neutrons in an aluminum ion can vary depending on the isotope. The most common isotope of aluminum is 27Al, which has 14 neutrons. However, other isotopes of aluminum exist with different numbers of neutrons.
The aluminum atom has 13 electrons and protons and also 14 neutrons.
Aluminum has 13 protons and 13 or 14 neutrons. Silicon has 14 protons, and 14 to 18 neutrons.

Aluminium-27 has 14 neutrons.

Aluminum has more neutrons than magnesium. The atomic number of aluminum is 13, which means it has 13 protons and typically 14 neutrons (in its most common isotope, aluminum-27). In contrast, magnesium has an atomic number of 12, with 12 protons and typically 12 neutrons (in its most common isotope, magnesium-24). Thus, aluminum has one more neutron than magnesium.
13 protons means it must be aluminum (Al). 15 neutrons means its atomic mass will be 28. This is not aluminum's most abundant isotope, but it is still aluminum.
When we encounter any naturally occurring atom of aluminum (Al), it usually has 14 neutrons in it. In very, very rare cases, an atom will have 13 neutrons in it. This is without regard to which ionic form the atom of aluminum will take.In the ionic form of aluminum noted by Al+3, we know that this is an aluminim atom with three of electrons "loaned out" to give it an overall +3 charge. This notation does not, however, tell us specifically which isotope of aluminum we are investigating. We can only "guess" based on the fact that there is only a trace of any aluminum with 13 neutrons in it while almost all the aluminum atoms we might consider have 14 neutrons in them.
If the isotope existed, it would have 16 neutrons.
