The cation Al3+
A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
13 in the neutral atom, 10 in the Al3+ ion
13 protons and 14 neutrons. The fact that its an ion doesn't change that ... only the number of electrons.
Well, if you're asking about valence electrons, there are 3. Otherwise, there are a total of 13 electrons in a neutral Aluminum atom Electron Configuration [Al]: 2 - 8 - 3
A fluorine ion with atomic number 9 and 10 electrons has a charge of -1 because it has one extra electron as compared to the number of protons (10-9 = 1). Its symbol is F-.
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.
The symbol for the ion with 8 protons, 9 neutrons, and 10 electrons is ^17O.
A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
The noble gas that is isoelectronic with an aluminum ion is neon. Both the aluminum ion (Al^3+) and neon have 10 electrons.
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.
An Al3+ ion has 13 protons, making it aluminum, and has lost 3 electrons. Since the number of electrons in a neutral aluminum atom is 13, the Al3+ ion has 10 electrons in total.
An element with a +3 charge and 10 electrons must have an atomic number of 13, which corresponds to aluminum (Al). In its neutral state, aluminum has 13 electrons, but when it loses three electrons to achieve a +3 charge, it is left with 10 electrons. Therefore, the atomic symbol is Al.
