1) Where does light come from, and what causes it to be a particular color? Describe the process by which an atom emits a photon. Your description should include ALL of the following:

1. The definition of a photon
2.What causes an electron to move from its ground state to an excited state?
3.What happens when an electron drops from an excited state back to its ground state?

hey your not cool]      

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
