Why are there only two possible values for the spin quantum number?

There are only two possible values for the spin quantum number because an electron can spin only in 2 directions: clockwise and anticlockwise.

Why do the electrons within a specific orbital have different spins?

As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins. This means if one is assigned an up-spin ( +½), the other must be down-spin (-½). An explanation of this is that an electron has a magnetic field due to its spin.

Can an electron have 0 spin?

Because the p electrons are in different orbitals their spins are not necessarily paired, so the spin could be zero or it could be one.

Can the spin quantum number be 0?

Combinations of Quantum Numbers The principal quantum number (n) cannot be zero.

Why can’t electrons have the same spin?

The Pauli Exclusion Principle 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.

Why two electrons Cannot be accommodated with the parallel spin in the same orbital?

Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii)).

What has a spin of zero?

Since 2013, the Higgs boson with spin 0 has been considered proven to exist. It is the first scalar elementary particle (spin 0) known to exist in nature. Atomic nuclei have nuclear spin which may be either half-integer or integer, so that the nuclei may be either fermions or bosons.

What happens when spin quantum number is 0?

Spin Quantum Number (ms) An electron cannot have zero spin. We also represent spin with arrows ↑ or ↓. A single orbital can hold a maximum of two electrons and each must have opposite spin.

Why electron does not collapse in the nucleus?

The electrons revolve around the nucleus with a fixed energy level. These electrons cannot cross this energy level until an extra energy is supplied even if the energy is supplied to the system. And after losing energy, they come to ground level. But do not fall into the nucleus.
