What is quantum number?
The set of numbers used to describe the position and energy of the electron in an atom.
There are four quantum number: principal, azimuthal, magnetic and spin quantum numbers.
- Principal quantum number can be represented by (n) or range 1 ≤ n
- Azimuthal quantum number can be represented by (l) or range 0 ≤ l ≤ n-1
- Magnetic quantum number can be represented by (ml) or range -l ≤ ml ≤ l
- Spin quantum number can be represented by (ms) or range -s ≤ ms ≤ s
The principal quantum number describes the energy of an electron and the probable distance of the electron from the nucleus. Generally, it refers size and energy level of orbitals.
Orbital size characteristic is given by the principal quantum number. Hence, option A is correct.
