What are quantum numbers?
- Quantum numbers are used to describe where around a nucleus a particular electron can be found.
- In any given atom, each electron can be described by four quantum numbers.
- These are n,l,m1,ms
- The values that each number can be are based on a set of rules.
What is a magnetic quantum number ?
- It describes the orientation of the orbitals.
- It is represented as ml.
- The value of this quantum number ranges from (-l to +l).
- When l = 2, the value of will be -2, -1, 0, +1, +2.
