☆☆☆☆☆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.
A method of obtaining an emission spectrum from a sample
The frequency of a wave, represented by the letter f, is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The SI unit of cycles per second is called hertz or Hz. Hz can be expressed as a reciprocal second (s-1 or 1/s).
The number of waves that pass a point in 1 second
If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
