Question

write electronic configuration
of o,CI ,Ca​

Answer 1

Explanation:

Oxygen

Number of electrons = 8

Electronic configuration = K= 2,L= 6

Cl, Chlorine

Number of electrons = 17

Electronic configuration = K= 2,L=8,M= 7

Ca, Calcium

number of electrons = 20

Electronic configuration = K= 2,L= 8,M= 8,N= 2

hope it helps ✌

Answer 2

Answer:

O means Oxygen

Atomic no. of O => 8

8 => 2, 6

Electronic configuration of O is 2,8.

Cl => Chlorine

Atomic no. = 17

17 => 2, 8, 7

Electronic configuration of Cl is 2,8,7.

Ca => Calcium

Atomic no. = 20

20 => 2, 8, 8, 2

Electronic configuration of Ca is 2,8,8,2.
