1. Which of the following statements about the properties of elements related to an atomic emission spectrum are true? Select all that apply. A. 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.
B. An atomic Ă©mission spectrum occurs when an element in the solid state absorbs energy, and emits light which corresponds to the energies of specific electrons.
C. 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.
D. 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.
E. An atomic emission spectrum shows the pattern formed when light absorbed by an element is separated into its different component wavelengths.
F. An atomic emission spectrum shows the pattern formed when light emitted by an element is separated into its different component wavelengths.

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
