Answer:

In isotope, atomic number of element remains same but mass number changes.

Atomic Number of Aluminium = 13

Atomic Mass of Aluminium according to the isotope given here = 27

No. of Protons = No. of Electrons = Atomic Number

No. of Protons = 13

No. of Electrons = 3

Atomic Mass = No. of protons + No. of Neutrons

No. of neutrons = Atomic Mass - No. of Protons

= 27 - 13

= 14
