Explanation: Have a great day :)
Al atom has 13 protons, 13 electrons.
Mass number = number protons + number neutrons
27 = 13 + number neutrons,
number neutrons =27 - 13 = 14 neutrons .
Ion Al³⁺, lost 3 electrons.
So, in Al³⁺, 13-3=10 electrons.
So, ion Al³⁺ has 13 protons,14 neutrons, 10 electrons.
