Question

Calculate the energy for the transition of an electron from the n = 5 level to the n = 4 level of a hydrogen atom.

Answer 1

The energy for the transition of an electron from the n = 5 level to the n = 4 level of a hydrogen atom is -0.159 eV.

Step-by-step explanation:

The energy for the transition of an electron from the n = 5 level to the n = 4 level of a hydrogen atom can be calculated using the formula:

`ΔE = -13.6 eV * ((1/4^2)-(1/5^2))`

Plugging in the values, we get:

ΔE = -13.6 eV * (1/16 - 1/25) = -0.159 eV

Therefore, the energy for the electron transition is -0.159 eV.
