- AAll are metals.
- BAll are non metals.
- CAll are metalloid.
- ✓They have half$-$filled electronic configuration.
✓
Answer
Correct option: D.
They have half$-$filled electronic configuration.
$\text{IV A}$ group has half filled valence shell like carbon or silicon and it shares it with the hydrogen singly filled $s$ orbital. They resemble have comparable $I.P.$ and $E.A.$
