Answer:

Here's what I get.

Explanation:

Quantum numbers

(a) 3 0 0

#n = 3# tells you that this is the third energy level and #l=0# tells that it is an #"s"# orbtal.

Together they tell you that this is a #"3s"# electron.

(b) 2 1 1

The principal quantum number #n = 2# tells you that this is the second energy level and #l = 1# tells you that it is a #"p"# orbital.

Together they tell you that this is a #"2p"# electron.

The magnetic quantum number #m_l = 1# tells you the orientation of the orbital in a magnetic field.

Thus the electron is in one of the three #"3p"# orbitals.

(c) 4 2- 1

Impossible! You cannot have #l = "-2"#.

The allowed values go from #l = 0# to #n-1# (i.e. #l = 0, 1, 2, 3#)

(d) 3 3 2

Impossible! You cannot have #l = "3"#.

The allowed values go from #l = 0# to #n-1# (i.e. #l = 0, 1, 2#)

(e) 3 1 2

Impossible! You cannot have #m_l = "2"#.

The allowed values of #m_l # go from #"-"l# to #"+"l# (i.e. #m_l = -1, 0, 1#).
