A

`1^(st)`,third

B

`3^(rd)`,third

C

`2^(nd)`, third

D

`2^(nd)`, second

Text Solution

Verified by Experts

The correct Answer is:
C
Electronic configuration `(Z = 12)=1s^(2) 2s^(2) 2p^(6) 3s^(2)`
The element has 2 valence electrons i.e., it belongs to Group 2.
The element has 3rd shell as valence shell i.e., it is belongs to 3 period.
