With regard to photoelectric effect, identify the correct statement among the following.
1 Number of electrons ejected increases with the increase in the frequency of incident light.
2 Number of electrons ejected increases with the increase in work function.
3 Number of electrons ejected increases with the increase in the intensity of incident light.
4 Energy of electrons ejected increases with the increase in the intensity of incident light.
Explanation:
(c) Number of ejected electrons is directly proportional to intensity of incident light.

The correct set of quantum numbers for the unpaired electron of chlorine atom is
1 \(2,0,0,+\frac{1}{2}\)
2 \(3,0,0, \pm \frac{1}{2}\)
3 \(2,1,-1,+\frac{1}{2}\)
4 \(3,1,1, \pm \frac{1}{2}\)
Explanation:
(d) Electronic configuration of \(\mathrm{Cl}(Z=17)\) atom :
\(1 s^2 2 s^2 2 p^6 3 s^2 3 p^5\)
So, the unpaired electron of Cl atom is in \(3 p\)-orbital. Hence, quantum numbers for unpaired electron; \(n=3, l=1\) (for \(p\)-orbital),
\(m=+1,0,-1\) and \(s= \pm 1 / 2\)
Thus, only possible set is \(3,1,1, \pm 1 / 2\).
