The electronic configuration of metl M i...

The electronic configuration of metl M is `1s^(2)2s^(2)2p^(6)3s^(1)`. The formula of its oxide will

A

`MO`

B

`M_(2)O`

C

`SO_(3)`

D

all of these

Text Solution

Verified by Experts

The correct Answer is:
B
Electronic configuration reveals it is monovalent (in fact Na) hence its oxide will be `M_(2)O`.
