Question

2.) Which transition in a hydrogen atom would absorb the photon of greatest frequency?

n = 3 to n = 1

n = 6 to n = 2

n = 2 to n = 9

n = 35 to n = 2

n = 12 to n = 6

n = 1 to n = 4

***NOT n=2 to n=9***

Answer 1

the energy level of an electron in a 'H' is represented by the integer "n" . the lowest possible energy of an atom .The lowest possible energy level of an electron is represented by, n=1 .

we know that energy of a poton is directly proportional to its frequency .

(as u mention not n=2 to n=9) SOwe are left with (n=1 to n=4) absorb photon of gratest energy

rest shows a drop in energy so no proton absorption will occur for them ( in these cases a proton is emmited to get lower energy state )
