Question

Consider hydrogen energy level transitions

Make a general statement about the relative energy values of all the possible hydrogen electron transitions, the likelihood of the different transitions happening, and what you think the hydrogen emission spectrum would look like.

Answer 1

When the electrons come from very high value of n, the energy emitted by the hydrogen will be equal to

En - E1 = (-13.6)/n^2 + 13.6/1^2 = 13.6eV

E2 - E1 = (-13.6)/2^2 + 13.6/1^2 = 10.2eV

E3 - E1 = (-13.6)/3^2 + 13.6/1^2 = 12.08eV

E3-E2 = (-13.6)/3^2 + 13.6/2^2 = 1.88 eV

All the transitions of the relative energy will vary from the range of 0eV to 13.6eV

Hydrogen emission spectrum in the visible regions has wavelength equal to 410 nm, 434 nm, 486 nm and 656 nm
