Question

Choose the correct option for the quantum numbers of the last electron of k plus

Answer 1

k⁽+¹⁾ =1s²2s²2p⁶3s²3p⁶
the last electron is in 3p orbital

Answer 2

Explanation:

Electric Configuration of K*+ =1s2 2s2 2p6 3s2 3p6

for last electrion shell will be also be taken last

so we will take 3p6

in 3p6

N=3

l=1(p=1)

value of M can be -1,0,+1

it is asked for last electron

so value of M is +1

Value of S can be +0.5 and -0.5 so

We have 2 correct sequence

1. 3,1,1,+0.5. 2. 3,1,1,-0.5
