Question

which of the following statements about the properties of elements related to an atomic emission spectrum are true? select all that apply. an atomic emission spectrum occurs when an element in the solid state absorbs energy, and emits light which corresponds to the energies of specific electrons. an atomic emission spectrum shows the pattern formed when light absorbed by an element is separated into its different component wavelengths. the light that an element emits is made up of an unlimited number of narrow lines of light that produce several different patterns or atomic emissions spectra for each element. an atomic emission spectrum shows the pattern formed when light emitted by an element is separated into its different component wavelengths. an atomic emission spectrum occurs when an element in the gas state absorbs energy, and emits light which corresponds to the energies of specific electrons. the light that an element emits is made up of a limited number of narrow lines of light that produce a unique pattern or atomic emissions spectrum for that element.

Explanation:

• For the first option: Atomic emission spectra occur when elements are in the gas state, not solid. So this is false.
• For the second option: Atomic emission spectra are about light emitted, not absorbed. So this is false.
• For the third option: Each element has a unique atomic emission spectrum with a limited number of lines. So this is false.
• For the fourth option: An atomic emission spectrum is indeed the pattern formed when light emitted by an element is separated into its component wavelengths. So this is true.
• For the fifth option: Atomic emission spectra occur when elements in the gas state absorb energy and emit light corresponding to electron energies. So this is true.
• For the sixth option: Each element has a unique atomic emission spectrum with a limited number of narrow - line light. So this is true.

Answer:

D. An atomic emission spectrum shows the pattern formed when light emitted by an element is separated into its different component wavelengths.
E. An atomic emission spectrum occurs when an element in the gas state absorbs energy, and emits light which corresponds to the energies of specific electrons.
F. The light that an element emits is made up of a limited number of narrow lines of light that produce a unique pattern or atomic emissions spectrum for that element.
