Question

The atom having the valence shell electronic configuration $4s^{2}4p^2$ would be in?

• A. Group 2 or II A and period 3
• B. Group 12 or II-B and period 4
• C. Group 14 or IV-A and period 4
• D. Group 14 or IV-A and period 3

Answer 1

The correct option is C Group 14 or IV-A and period 4

There are 4 electrons in the outermost shell.

So, it belongs to ${14}^{th}$ or IV-A.

The outermost electron is in 4p, so it belongs to the $4^{th}$ period.
