Question

Three of the strongest lines in the He+ ion spectrum are observed at the following wavelength:
(1) 11.397 nm
(2) 54.030 nm
(3) 72.941 nm

Find the quantum numbers of the initial and final states for the transitions that give rise to these three lines. Do this by calculating, the wavelengths of lines that can originate from transitions involving any two of the four lowest levels. When a calculated wavelength matches an observed one, write down n-hi and n-lo for that line. Continue until you have assigned all three of the lines.

Answer 1

(1) __________ ----> _________
(2) __________ ----> _________
(3) __________ ----> _________
fill in lines

Answer 2

ok so your giving us the wavelengths then asking us to match them to a wavelenght?

Answer 3

no its saying find the quantum numbers of initial and final states

Answer 4

alright so by quantized number are you trying to find the energy of a proton? I'm confused one what your looking for here.

Answer 5

well first it says to find the wavelengths then it says find the hi and low of the wavelength line

Answer 6

im confused on the instructions myself but whatever the question is in front of you

Answer 7

alright well the 3 numbers you gave were the wavelength so pick the bigest and smallest

Answer 8

so the 72.941 is the biggest and the 11.397 would be the smallest

Answer 9

yea thats what i would say

Answer 10

so how exactly would i solve the problems

Answer 11

well seeing as they gave you the wavelength and then asked you for a wavelenght there isn't anything to solve besides saying one is bigger than the other.

Answer 12

but it says find the quantum numbers

Answer 13

what level of chemistry are you in right now? This could get deep.

Answer 14

im in college chem just general chem

Answer 15

Ok so a wavelength is used to calculate the energy of a proton, which a He atom can only produce a specific different colors (wavelengths) because it involves an excited electron falling from a higher energy state to a lower energy state. This is called being quantized meaning that unlike speeding up in a car where you hit ever possiblitity between 1 and 50 you only hit a few 1, 3, 50... So this quantum number the only thing i can think that your teacher is asking is for the energy of the proton. which would be found by using the following equation
c=h(lamda)

Answer 16

but regardless of that it's directly proportional so the little number is going to be the smallest and the bigest number will be the biggest

Answer 17

that does not help much but thanks for trying.
