Atomic number of Alis 13 and mass number...

Atomic number of Alis 13 and mass number is 27 .Calculate the number of electrons protons and neutrons in the ion formed Represent the ion.What will be its valency?

Text Solution

Verified by Experts

Atopmic no of AL(z) =13
Mass no of AL (z) =27
No of electons present =13
Distribution of electrons = K(2)L(8)N(3) ltrbgt No of electrons present in `AI^(3+)` ion = K(2)L(8)
Nop of protons present in `AL^(3+)`=13
No of neutorns present in `AI^(3+)` ion =27-13=14
Valency of `AI^(3+)` ion =3
