write orbital notation for electrons in orbital with the following Quantum number 1) n=2, l=1 b) n=4 ,l= 2 c) n=3 , l= 2
Answers
Answer:
option c) is correct
Explanation:
The interesting thing to notice here is that you can't really say the exact orbital in which that electron resides because you're missing the value of the magnetic quantum number,
m
l
.
As you know, four quantum numbers are used to describe the position and spin of an electron inside an atom.
The principal quantum number,
n
, describes the energy level on which the electron resides. In your case, you have
n
=
3
→
the third energy level
The angular momentum quantum number,
l
, describes the subshell in which the electron is located. You have
l
=
0
→
the s subshell
l
=
1
→
the p subshell
l
=
2
→
the d subshell
⋮
In your case, the electron is located in the
p
subshell. Now, the
p
subshell contains a total of
3
orbitals as described by the magnetic quantum number,
m
l
m
l
=
−
0
→
the
p
z
orbital
m
l
=
−
1
→
the
p
x
orbital
m
l
=
+
1
→
the
p
z
orbital
In order to be able to specify the exact orbital in which the electron resides, you need to know the value of
m
l
. Since that is not given to you, all you can say is that
n
=
3
,
l
=
1
The electron is located on the third energy level, in the p subshell.
