Question

If the orbital holds two electrons then they must have opposite spins.

• A. True
• B. False

Answer 1

The correct option is A True

Electrons are charged species which revolves around the nucleus and spin on their axis. Thus, they generate a magnetic field due to their motion. Two electrons present in the same orbital have opposite spins (i.e. clockwise and anticlockwise) to cancel out the magnetic field generated by the other electron.
