Question

If the spin quantum number has three possible value then maximum number of electrons in $p-$subshell will be

• A. $3$
• B. $6$
• C. $9$
• D. $12$

Answer 1

The correct option is C $9$

We know that $p$ subshell has $3$ orbitals and $1$ orbital can accommodate $2$ electrons into it as per the Pauli Exclusion Principle, which states that in an atom or molecule, no two electrons can have the same four electronic quantum numbers. Now according to the question if there are $3$ spin values possible then $3orbital\times 3spinvalues=9$ electrons are possible in $p$ subshell.

Option C is correct answer
