Hund rule of maximum multiplicity & numericals: Hund rule of maximum multiplicity: pairing of electron in various orbital of a subshell connot take place until each orbital contain ane electron. Numericals : 1.what is the total capacity of electron of 4th principal energy shell ? sol. the no. of electron in a shell =2n^2 where n =4 than 2×(4) ^2= 32 2.how many electron confit in principal shell n=2? Sol. no. of electron in a shell =2n^2 where n =2 than 2×(2) ^2= 8 3.how many electron can be accomodate in 4d subshell? Sol. d subshell have five orbital and each orbital can have 2 electron. so 4d subshell can accomodate 2×5= 10 electrons
