Question

what are the possible values of n and l for the unpaired electron in the atom of an element whose atomic number is 9​

Answer 1

Answer:

principle quantum no is 0,1,2,3,4,5,6,7,

l one less than n

Answer 2

Answer:

N=2

L=1

Explanation:

Atomic no. 9 - F

EC = 1S2 2S2 2P5

hence,

N = 2

L = 1

Ml = -1,0,1

Ms = +1/2 or -1/s
