Enter the nth level of the electron within the hydrogen atom into the calculator to determine the energy level.

Energy Level Formula

The following equation is used to calculate the Energy Level.

E = – 1/n^2 * 13.6eV

  • Where E is the energy
  • n is the nth level the electron orbits within the hydrogen atom

What is an Energy Level?

Definition:

An energy level is a fixed amount of energy that a system, such as molecules, atoms, electrons, etc., can have.

How to Calculate Energy Level?

Example Problem:

The following example outlines the steps and information needed to calculate Energy Level.

First, determine the nth level of the electron orbit in the hydrogen atom. For this example, the energy level is 3.

Next, use the formula above to calculate the energy level:

E = – 1/n^2 * 13.6eV

E = – 1/3^2 * 13.6eV

E = 2.421 e-19 Joules
