Elements of group 14...

Elements of group `14`

A

exhibit oxidation state of `+4` only

B

exhibit oxidation state of `+2` and `+4`

C

form `M^(-2)` and `M^(4+)` ions

D

form `M^(2+)` and `M^(4+)` ions

Text Solution

Verified by Experts

The correct Answer is:
B
They have valence shell electron configuration `ns^(2)np^(2)` , so two electrons of `p` sub shell or four elecrtrons of `s` and `p` sub shells can participate in chemical bonding.
