Respuesta :

Answer: 13 proton, 10 electron and 14 neutron.

Explanation: electron are 10 because 3 electrons are transfer to other atom.

Answer:

Proton = 13

Electron = 10

Neutron = 14

Explanation:

Al3+ means Al that  has lost 3 electrons. Al has 13 protrons and 13 electrons. Having lost 3 electrons, Al3+ is left with 10 electrons.

Neutron + protron = relative atomic number

n + 13 = 27

n = 27 - 13 = 14
