The electrons in a poly -electronic atom are filled one by one in roder fo increasing energy level . The enrgy fo subsgells and orientation depeds upon the values of three quantum numbers 9 i.e., n. l and m respectively derived from Schrodinger wave equation . The different orbitals fo a subsshells however possess same energy level and are called degenerater orbitals but their enrgy level charges in presenct of magentic field and the orbitals are non-degenerate . (A) spectral line is noticed it an electron jups form one level to tohere . the paramgnetic nature of eelment sis due to the presence of unpaired electron .
The number of spherical and angular nodes in ` 2p` orbitals are :

Options

A. `1,1`
B. `2,1`
C. `1,0`
D. `0,1`

Answer

D

Explanation

2p has ` n= 2 , l=1`
Spheircal node ` =n -l -1 =0`
angualr node ` =l=1`.
