A) The nuclear charge experienced by the electron in this state is less than 2e, where e is the magnitude of the electronic charge
B) It has 3 radial nodes
C) It is a 4d state
D) It has 2 angular nodes
Correct Answer: C , D
Solution :
\[{{\text{E}}_{n,}}2=\,-3.4e\text{V}=\,-\,13.6\times \frac{4}{{{n}^{2}}}\] \[l=2,\] \[\frac{1}{{{n}^{2}}}=13.6\times \frac{1}{4}\times \frac{1}{13.6\times 4}\] \[m=0,n=4;l=2\] No. of Radial Node \[=\,n-l-1\] \[=\,4\,-2\,-1\,=\,1.\]Solution :
