When electrons are found inside an atom, they're restricted to specific areas, or regions within the atom which can be described by orbitals. Let's see what this means in terms of quantum numbers.
Answer:
Electrons are "fermions", that means in any system can't be two of them having the same set of quantum numbers. The two electrons in the same orbital have two different spin quantum numbers ms and the same magnetic ( ml ), secondary ( l ) and principal ( n ) quantum numbers which are characteristic of the orbital.
