16.Like the visible spectrum,an atomic emission spectrum is a continuous
range of colors.
17.Each element has a unique atomic emission spectrum.
18.A flame test can be used to identify the presence of certain elements in
a compound.
19.The fact that only certain colors appear in an element’s atomic emission
spectrum indicates that only certain frequencies of light are emitted.
20.Atomic emission spectra can be explained by the wave model of light.
21.The neon atoms in a neon sign emit their characteristic color of light as
they absorb energy.
22.When an atom emits light,photons having certain specific energies are
being emitted.
