☆☆☆☆☆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
something that splits up light into different colors ! apx :)
what is the energy of J of photon with a wavelength of 601nm?
It has a specific set of possible values.
3.96 10-19 j
The emission spectrum of an element
F=v/&
The range of values of some property
an element becomes a totally different element..
ms= +1/2
The energy used to hold the nucleus together
5.98 x 10^14 Hz
The mass of a nucleus is subtracted from the sum of the masses of its individual components.
The wavelength is 671 nm.
Radioactive decay is the spontaneous breakdown of a nucleus into smaller parts.
4.78 x 10-19
4.5 × 1015 J
the electron energy levels
(Explanation): remember that if an atom has less than 20 protons, the closer the number of neutrons and protons are, the more stable it is. Since 10 is closest to 12 out of these options, D is the correct answer.
