What is the generic valence electron configuration for GroupIVA(14)?

Question

1. ns2np1
2. ns2np4
3. ns2np2
4. ns2np3
5. ns2np5

Answer 1

Hello, Caitlyn,

C is 1s²2s²2p²

Si is 1s²2s²2p²3s²3p²

Ge is 1s²2s²2p²3s²3p²4s²4p²

That's enough to see the pattern. I've highlighted the valence shells for each. We can see a pattern:

ns²np²
