Quantum Numbers Worksheet Label each of the following sets of four quantum numbers as either Valid, which indicates that set is a legitimate set of quantum numbers for an electron, or Invalid, which would indicate that the set is not a possible set of quantum numbers for an electron. (Hint: Check them with the rules on the quantum numbers handout you got) An electron is in a certain energy level where the maximum value of the quantum number l = 4. What energy level is the electron in? How does the size of a given type of orbital vary with n? How many orbitals are there in an h subshell (l=5)? What are their values of ml? Give the complete set of quantum numbers for all the electrons that could populate the 3d subshell of an atom.
Explanation / Answer
1 l=2*n-1
m = -l to +l
a) valid
b) valid
c) valid
d)not valid (here l =! 2*n-1)
e)valid
f)valid
g)valid
h)not valid (here m is not between -l to +l)
i)valid
j)not valid (here m is not between -l to +l)
2. l=2*n-1 , l=4
so , n=2.5 which is not true
thus n=2
3. as we move away from nucleus n increases with increase in radius
4. 11 as m ={-l to +l} ,here l=5
and possible value of m are -5,-4,-3,-2,-1,0,1,2,3,4,5
5. n=3
l can be from 0 to 5
m=+2,-2
