no of electrons = 13

no of neutrons = 27-13=14

Hope it helps you✌✌

Answer 2

Answer:

13

14

Explanation:

Atomic number of Al = 13

Number of electrons = number of protons = Atomic number

Hence number of electrons = 13

number of protons = 13

Mass number = 27

Mass number = Number of protons + number of neutrons

27 = 13 +number of neutrons

So, number of neutrons = 27 - 13 = 14
