Question

which of the following set of quantum numbers describe the electron that can be removed most easily from a Potassium atom in its ground state?
(A)n=3,l=1,m=1,s=-(1/2)
(B)n=4,l=0,m=0,s=+(1/2)
(C)n=2,l=1,m=0,s=-(1/2)
(D)n=4,l=1,m=1,s=+(1/2)​

Answer 1

Answer:

B) n=4, l=0, m=0, s=+1/2

Explanation:

Potassium (K) have valence electron at 4s and it can be removed most easily. So quantum number of 4s electron is n=4, l=0, m=0, s=+1/2.
