Question

In any subshell, the maximum number of electrons having same value of spin quantum number is:

• A. $\sqrt{l(l+1)}$
• B. $l+2$
• C. $2l+1$
• D. $4l+2$

Answer 1

The correct option is C $2l+1$

The maximum number of the electrons with the same spin of the same quantum number will be equal to the orbital since each orbital consist of maximum of two electrons is always of the opposite spins.

So it is given by $2l+1$.
