Chemical element whole number. For example, the relative atomic mass of chlorine is 35.453 u, which differs greatly from a whole number as it is an average of about 76% chlorine-35 and 24% chlorine-37. Whenever a relative atomic mass value differs by more than 1% from a whole number, it is due to this averaging effect, as significant amounts of more than one isotope are naturally present in a sample of that element. Chemists and nuclear scientists have different definitions of a "pure element". In chemistry, a pure element means a substance whose atoms all (or in practice almost all) have the
Shades of Green (resort) guests. In 1996, the resort was purchased outright, for $43 million, due to the high success of the resort, although Disney still owns the land on which the resort sits.

The resort previously had a small cafe located near the lobby called Cafe Belle and a lounge called the Back Porch.
