### Rydberg equation

Can someone explain what the rydberg equation tells us conceptually?

### Re: Rydberg equation

It tells us how much energy is being released (as light) when an electron shifts from one energy level to another, with "n" representing the energy level. We can expect the answer to be negative when energy is being released (and the electron moves closer to the nucleus) and positive when energy is being absorbed (and the electron moves away from the nucleus).

It applies specifically to hydrogen atoms only and tells us how much energy is needed to bring an electron from the energy state n to the next lower energy state.

### Re: Rydberg equation

The way I thought of it was that the energy that you find using this equation is the amount of energy that the electron gives off in order to return to a previous energy level. This is why the number is typically negative as well. The energy is the amount the it gives off say from the 6th energy level to the 3rd for example.

Is this the equation Lavelle told us to steer away from using because students usually make mistakes?
