Al2+ has 13 protons
Al itself has 13 electrons and 13 protons, 2+ means that Al has ''lost'' 2 electrons(and now have 11 electrons), the number of protons stays the same(13)
Added:By the way, it is more common to take Al3+ as example, because Al has 3 valence electrons (in its outer shell) to donate to eg. oxygen: Al2O3 is formed.

What is the formula of the ion that has 13 protons and 10 electrons?
The ion with 13 protons and 10 electrons would have a 3+ charge since there are more protons than electrons. Its formula would be Al3+, representing an aluminum ion with a 3+ charge.
How many protons and electrons are in Aluminum3?
Aluminum's, or Al's, atomic number is 13. Therefore, an electrically neutral aluminum atom would have 13 protons and 13 electrons. However, Al3+ has 3 less electrons than neutral aluminum, an thus only has 10 electrons.
Aluminum ion has how many electrons?
An aluminum ion, Al3+, has 10 electrons. This is because aluminum normally has 13 protons and 13 electrons in a neutral atom, but in the +3 ion it loses 3 electrons, leaving it with 10 electrons.

What does the symbol Al3 plus tell you?
The symbol Al3+ refers to an aluminum ion that has a positive charge of 3. This means it has lost three electrons to achieve a more stable electron configuration.
