What is a flame test

Answer By exposing materials to a hot flame (from a Bunsen burner typically), the color of the flame can be used to identify the material. Certain elements give off a characteristic color when heated to high temperature. See the Related Links for "Wikipedia: flame test" to the bottom for the answer.

Outline on nuclear energy

Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion

What is the nuclear decay equation for an example of alpha decay

The equation for the alpha decay of 239Pu is: 94239Pu --> 92235U + 24He

where 24He represents the alpha particle, which is a Helium nucleus.
