Vedclass · Answer

(B) For a given principal quantum number $n$,the total number of orbitals is given by $n^{2}$.For $n=5$,the total number of orbitals is $5^{2} = 25$.Each orbital can hold a maximum of two electrons with opposite spins ($m_s = +\frac{1}{2}$ and $m_s = -\frac{1}{2}$).Therefore,the number of orbitals associated with $m_s = +\frac{1}{2}$ is exactly equal to the total number of orbitals,which is $25$.

The number of orbitals associated with quantum numbers $n=5, m_s=+\frac{1}{2}$ is
