Describe observations that led to the bohr and quantum models of the atom.
explain how line spectra are used to identify elements and what they indicate about atoms.

The Bohr model was based on the observations of the atomic emissions spectrum of the hydrogen atom. When white light is diffracted with a prism, all the colors of the visible spectrum can be seen. Each color corresponds to a specific amount of energy; however when the light given off by the hydrogen atom was passed through a prism, only certain colors of light could be seen. This led Bohr to theorize that electrons only have certain energies in an atom and they had to be in energy levels.

Organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
