Electrons+and+energy

LT 14: I can explain how the energy of an electron changes as it moves closer or farther away from the nucleus.

Today, you will learn about who created the first model of hydrogen and what happens as the electrons move within the electron cloud.

The truth is, electrons don't ever stay in the same place. They are always moving, jumping, falling.

First, let's look at a scientist named Niels Bohr.

Unfortunately, the model that Niels Bohr made only worked with Hydrogen. But, what is interesting is that this rising and falling of the electrons allows each element to have its own unique signature.
