first of all, thank you for posting this question. i am happy to see someone having same questions like me
its been more then one year you have posted this question so I am not sure if you still need to answer
but please let me share my views
answer E sayis that they will 'promote' the discrete quantal amounts of energy whereas it is the 'electrons' that get 'promoted' , not the quantals of energy.
in other words,
quantal amounts of energy - described as- required to excite electrons
electrons - described as - get promoted to next level
this might because i know abt the electron energy orbits in atom (my mother is chemistry teacher!)
but this very confusing question will help me realise tactic to focus on words in case of other non-familiar topics
my problem is that i dont have time to type put the entire paragraphs and questions as they are very long, i cudnt find them on internet to copy paste.
so I hope to find someone having the same book im reading, that is the Barrons 12th edition
I am not sure if i should expect a quick reply here as you might not be into this anymore, but if you can guide me to get my answers it would be realy great help
thanks in advance
