th
electron is the one marked blue
Quantum numbers of
15
th
electron are
Principle quantum number
(
n
)
=
3
Because it’s in
3
rd
shell
Angular momentum quantum number
(
l
)
=
1
Because it’s in p-subshell
Magnetic momentum quantum number
(
m
)
=
±
1
p
z
corresponds to
m = 0
orbital,
p
x
and
p
y
are mixtures of
m = +1
and
m = -1
orbitals.
Spin quantum number
(
s
)
=
+
1
2
Because it’s the first electron in the
3p
y
orbital.
