Number of protons in Al^3+ are 13 and number of electrons are 10.

  • Every atom has a proton, a subatomic particle, in its nucleus. The particle is electrically charged positively.
  • A negatively charged subatomic particle known as an electron can either be free or attached to an atom.
  • The number of protons in the nucleus is equal to the atomic number.
  • The number of electrons in a neutral atom is equal to the number of protons.

Here aluminium is not an atom. it is presented as ion.

Atomic number of aluminium is 13

therefore, number of proton = 13

This aluminium ion Al^3+ has a positive charge of three. Aluminum, which has an atomic number of 13, has lost three electrons when it has a positive charge of 3.

therefore number of electrons in aluminium ion = 13 - 3 = 10

+3 charge will not affect the number of proton. thus number of proton will remain same as atomic number of aluminium.

Therefore, number of proton in aluminium ion are 13 and number of electrons in aluminium ion are 10.
