Question

Why do the electrons in the orbitals move in opposite directions according to spin quantum number??

Answer 1

 Pauli Exclusion Principle which states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.

When electrons that have opposite spins are put together, there is no net magnetic field because the positive and negative spins cancel each other out. If an atom has an odd number of electrons, the one un-paired electron will determine the spin.

Answer 2

Electrons in the orbitals move in opposite directions as per Pauli exclusion principle

• The intrinsic rotational momentum, or spin, of an electron, is represented by the spin quantum number, commonly referred to as the electron spin.
• Because electrons are fundamental particles with a spin half, their quantum state can be either spin up or spin down.
• The concept is based on the Pauli Exclusion Principle.
• Only two electrons can fit into an orbital at a time, hence they must have opposing spins.
• There is no net magnetic field when oppositely spinning electrons are combined because the positive and negative spins cancel one another out.
• When oppositely rotating atoms are united, the positive and negative loops neutralize each other out, hence there is no net magnetic field.
