Answer» Solution :Thenumber of electronto befilledin variousorbitalsis restricited bythe exclusion principlegiven by theaustrianscientistwolfgangPauli(1926) Rule:No twoelectrons inatom can have thesamesetof fourquantumnumbers. Secondmethod :Only twoelectronmayexisthaveoppositespin. Used: pauliexclusionprincipleon the numbercapacityof electronto bepresent in anysubshell. Subshellincomprisesof oneorbitaland thus themaximumnumberof electronpresentin 1ssubshellcan be TWO Sub shell 4hadfiveorbitalsso itcan ACCOMODATE 10electrons  ifprinciplequantumnumbern thus numberoforbitalsin N=`n^(2)` Maximumnumberof electronin n= `2n ^(2)` Example: The electronconfigurationof He is`1s^(2) ` forthis twoelectronthe VALUEOF `n,1,m` is1,0,0,itsspin quantumnumber`+(1)/(2)` and`(1)/(2) `are differ from eachotherwithoppositespin |
