The Bohr model — its really not boring

Have you ever bought color crystals for your fireplace — to make flames of different colors Or have you ever watched fireworks and wondered where the colors came from  

Color comes from different elements. If you sprinkle table salt — or any salt containing sodium — on a fire, you get a yellow color. Salts that contain copper give a greenish-blue flame. And if you look at the flames through a 

Niels Bohr, a Danish scientist, explained this line spectrum while developing a model for the atom. 

Bohr found that the closer an electron is to the nucleus, the less energy it needs, but the farther away it is, the more energy it needs. So Bohr numbered the electron s energy levels. The higher the energy-level number, the farther away the electron is from the nucleus — and the higher the energy. 

Bohr also found that the various energy levels can hold differing numbers of electrons energy level 1 may hold up to 2 electrons, energy level 2 may hold up to 8 electrons, and so on.
