1.	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 :A. `1,1`B. `2,1`C. `1,0`D. `0,1`
Answer» Correct Answer - D 2p has ` n= 2 , l=1` Spheircal node ` =n -l -1 =0` angualr node ` =l=1`.
