Bohr Models

Hello, everyone!

We are back and we are going to talk about Bohr Models!

But first, lets remember who Bohr is.



This is Niels Bohr. He was born in October 7, 1885 and died in November 17, 1962.

He was important in chemistry because of his Bohr models.



This is the Bohr model of hydrogen. This diagram outlines the electrons from one orbital to another and that creates an energy(photons) which is emitted from the atom.

The strength of the energy is determined by the wavelengths (as shown below).


Based on this theory, he determined that each atom has a specific colour patterns or spectra of light.



From this we can determine that electrons are in orbitals. When they absorb energy, the electrons move up orbitals and when they emit energy, they move down.

Lets remember the basics of how to draw the Bohr model.




And remember, the first orbital contains 2 electrons and 2nd and 3rd orbitals contain 8 electrons.

Thats a wrap!
