Question
The radii of maximum probability for $$3s, 3p$$ and $$3d$$ electrons are in the order
A.
$${\left( {{r_{\max }}} \right)_{3d}} > {\left( {{r_{\max }}} \right)_{3p}} > {\left( {{r_{\max }}} \right)_{3s}}$$
B.
$${\left( {{r_{\max }}} \right)_{3d}} > {\left( {{r_{\max }}} \right)_{3s}} > {\left( {{r_{\max }}} \right)_{3p}}$$
C.
$${\left( {{r_{\max }}} \right)_{3s}} > {\left( {{r_{\max }}} \right)_{3p}} > {\left( {{r_{\max }}} \right)_{3d}}$$
D.
$${\text{none of these}}$$
Answer :
$${\left( {{r_{\max }}} \right)_{3s}} > {\left( {{r_{\max }}} \right)_{3p}} > {\left( {{r_{\max }}} \right)_{3d}}$$
Solution :
Radius of maximum probability decrease with increase in azimuthal quantum no.
