Question

The atomic number of sodium is 11 give the values of n,1m and s for the valence electron of sodium

Answer 1

Explanation:

Atomic number of sodium is 11.

so, it's electronic configuration will be 1s2 2s2 2p6 3s1.

since valence electron of sodium enters in to 3s-orbital we have,

Value of (n) is 3.

Value of (l) is 0. (for s-orbital l=0).

since l is 0 , m is also 0. (m= -l to +l).

spin value (s) = +1/2(or)-1/2.
