Answer 1

Explanation:

1. Electronic Configuration of Aluminium is 2,8,3 and it's valency is 3
2. Electronic Configuration of Ferrous is 2,7 and it's valency is 1
3. Electronic Configuration of Argon is 2,8,8 and it's valency is 0

Answer 2

Heya!!

Here is your answer -

i. Aluminum =

(electronic configuration - 2,8,3)

(valency - 3)

(period number - 3)

(Group number - 13)

ii. Fluorine =

(electronic configuration - 2,7)

(valency - 1)

(period number -2)

(Group number - 17)

iii. Argon =

(electronic configuration - 2,8,8)

(valency - 0)

(period number - 3)

(Group number - 18)
