Which one of the following elements exhibit maximum number of velence electrons ?

A

Na

B

Al

C

Si

D

P

Text Solution

Verified by Experts

The correct Answer is:
D

Thus, Na (group 1) has one, Al (group 13) has three (13-10), Si (group 14) has four (14-10) and P (group 15) has five (15-10) valence electrons. Therefore, P has maximum number of valence electrons i.e., 5 (maximum among the given).
