1.	What is the maximumnumber ofemissionlineswhen theexcitedelectronof a H atominn=16dropsto thegroundstate ?
Answer» Solution :Numberof emissionlines `=(n(n-1))/( 2 )` `=(6(6-1))/(2) =15` followingtransitionare occur : (i) n=6 to n=1 `6 to 5, 6 to4,6 to3,6 to 2,6 to 1` (ii)5 to4 ,5 to 3,5 to 2,5 to 1 so (iii) n=4ton= 1 so `n_(4) to n_(3)n_(4)to n_(2)n_(4) to n_(1)` (IV)n=3ton=1so `n_(3)to n_(2) ` and`n_(3)to n_(1) so` (v ) `n_(2) to ` n=1 so ONE Total5 + 5+3 +2 +1=15transitionso 15 emissionlinesobtain
