a) Calculated E1 = 5.99eV and E2 = 8.49eV as energies given off
b) From ground state, -10.0eV + 5.99eV gives me -4.01eV
-10.0eV + 8.49315 gives me = -1.50685eV
Meaning on my diagram, the first excited state would be -4.01eV and second being -1.50685
d) using lambda = (hc/E)
I first find...
So to try this again.
For part a)
E1 from 207nm lambda comes out to be 5.99 and E2 from 146nm to be 8.4935
For part b)
You draw those two levels as excited states on the diagram
Then for part d)
I keep thinking of using the same (1/lambda) equation to find the wavelength with nf...
1. Problem:
The ground-state energy of a hypothetical atom is at -10.0eV. When these atoms, in the ground state, are illuminated with light, only the wavelengths of 207 nanometers and 146 nanometers are absorbed by the light atoms (1 nanometer = 10^-9meters).
(a)Calculate the energies of...
