Question

Write a set of quantum numbers for each of the electrons with an nof 4 in a Se atom

Short answer

n	l	m	s
4	0	0	+1/2
4	0	0	-1/2
4	1	-1	+1/2
4	1	-1	-1/2
4	1	0	+1/2
4	1	1	+1/2

Step-by-step solution

drawing the orbital diagram

We can see that there are 6 electrons in n = 4 in a Se atom.

writing a set of quantum numbers for each of the electrons with an n = 4 in a Se atom  

a set of quantum numbers for each of the electrons with an n = 4 in a Se atom is mentioned in the table below,

n	l	m	s
4	0	0	+1/2
4	0	0	-1/2
4	1	-1	+1/2
4	1	-1	-1/2
4	1	0	+1/2
4	1	1	+1/2
