I need a step by step answer on how to solve problem 11.25 Iattached the question from the book and answers that the back ofthe book gave me but I need someone to explain how and why you getthose answers, thanks.
on part b I understand the Îstot=0, but how does therule Îl=+/- 1 work?
-do the states on left collum (1s2, 1s2s, 1s3s) allhave l=0 and the ones on right collum (1s2p, 1s3p) all have a l=1then?
in part c What does mestastable mean, and how do you know whenit is?
-Does mestastable mean it has no where else to decay or what,and if so then why isn't 1s2 mestastable, is it becauseit's not an excited level, and how do you decide which ones areexcited levels?
