When an electron move from one level to another an amount of energy is dissipated. Give the equation that will enable you to calculate that amount of energy

well of course there is the energy of the emitted photon E = h f

but if they really want you to calculate the change in energy from one level to another that gets pretty complicated once you get beyond the Bohr model of the Hydrogen atom.

I answered this question for you a day or so ago. Why are you asking it again?

The amount of energy dissipated when an electron moves from one energy level to another can be calculated using the equation:

ΔE = E2 - E1

In this equation, ΔE represents the change in energy, E2 is the final energy level, and E1 is the initial energy level.

To use this equation, you need to know the energy levels of the electron in its initial and final states. The energy levels of electrons in an atom or a molecule are quantized and can be described using the concept of energy levels or shells. The energy levels are represented by integer values, typically denoted by n=1, 2, 3, and so on.

For example, if you know that the electron is moving from energy level n=2 to n=3, you can substitute these values into the equation as follows:

ΔE = E3 - E2

By knowing the specific energy values associated with each energy level (which depends on the system or context you are considering, such as atoms or molecules), you can calculate the amount of energy dissipated when an electron moves between energy levels.
