Atoms emit visible and ultraviolet light asthey are:. a. heated and the solid melts to form a liquid
b. the atoms condense from a gas to a liquid
c. the electrons move about the atom within an orbit
d. electrons jump from lower energy levels to higher levels
e. electrons jump from higher energy levels to lower levels

e. electrons jump from higher energy levels to lower levels

Explanation:

Atoms emit visible and ultraviolet light as electrons fall from higher levels to lower level. Whenever there is a fall from a higher level to  lower level, the electron loses energy that is equivalent to the energy difference of the two energy levels. This energy manifests itself as light which includes Visible and UV light. The correct option is; E.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
