Identify the correct statement
(A) According to Hund's rule each orbital should be filled with single unpaired electron before pairing
(B) For any orbital,value of "(m)+I" can't exceed its value of "n"
(C) Monovalent cation of any transition element can't have more than "5" unpaired electrons.
(D) `Al^(3+)` has "4" electron having sum of their quantum number "n+m+l=2" .

Can an electron have the quatum number values as n = 2, l = 2 and m = +2 ?

the highest probability of finding the electron in an orbital having values of quantum hnumbers n=3 l=1 and m=1.

An electron having the quantum numbers n=4, l=3 , m=0 , s=-1/2 would be in the orbital

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 fo 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 ion having maximum number of unpaired eelctrons is :

Mu on (mu^(-)) is a negatively charged (|q|=|e|) particle with a mas m_(mu)=200 m_(e ) where m_(e ) is the mass of the electron and e is the electronic charge . If mu^(-) is bound to a proton to from a hgydrogen like atom identify the correct statements (A) Radius of the muonic orbit is 200 times smaller than that of the electron (B) The speed of the mu^(-) in the n^(th) orbit is 1/200 times that of the electron in the n^(th) orbit (c )The ionizaion energy of muonic atom is 200 times more than that of an hydrogen atom (D) The momentum of the muon in the m^(th) orbit is 200 times more than that of the electron
