The question is incomplete; the complete question is;
There are 118 known elements. How many elements have atoms, in their ground state, with core electrons whose quantum numbers are n=3 and l=1?
a. 10
b. 6
c. 100
d. 18
Answer:
c. 100
Explanation:
If we look closely at the periodic table, we will notice that there 100 elements that occur after argon whose electronic configuration is; 1s2 2s2 2p6 3s2 3p6.
This means that there every other element after argon must have a 3p sublevel as part of its core electrons. In the 3p sublevel, n=3 and l=1.
If we diligently count the number of elements from potassium (immediately after argon) to Oganesson (element 118) we have a total of 100 elements all having core electrons of quantum numbers are n=3 and l=1.

Periodic table:
It is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number.
There 100 elements that occur after argon whose electronic configuration is: [tex]1s^2 2s^2 2p^6 3s^2 3p^6[/tex]
- There are total 6 electrons can fit for n=3 and l=1.
- If the value of third shell is 3 or n=3 with sub-shell value l=1.
- The value of n=3 and l =1 suggest that it is a 3p orbital while the value of m1 = 0 [magnetic quantum number] shows that the given 3p orbital is 3pz in nature.
This means that there every other element after argon must have a 3p sublevel as part of its core electrons. In the 3p sublevel, n=3 and l=1.
Thus, correct option is c.
