Question

How would you find out the number of electrons from just the 4 quantum numbers?

Answer 1

The quantum numbers are going to explain how many electrons are there in a particular element and will give a lot of information about the spin of the electrons and the location of the electron around the nucleus.

Complete answer:
- In the question it is asked how we can find the number of electrons by using four quantum numbers.
- The principal quantum number (n) will give information about the energy level in which electrons are residing.
- The angular momentum quantum number (l) will give information about the subshell in which electrons are present.
- The magnetic quantum number (m) will give information about the exact orbital where we can find the electron.
-The spin quantum number (s) will give information about the spin of the electron.
- By using the information from the four quantum numbers, we can say about the number of electrons present in the given atom.
- All the electrons present in an atom do not have the four quantum numbers same.
- The quantum numbers will give the complete information about the electrons present in an atom.

Note: The principal quantum number will give the information about the number of energy levels present in the given compound. Every energy level contains subshells also. We have to consider all the subshells while calculating the number of electrons present in an atom.
