All stars are composed of a mixture of elements. When these elements are heated they emit specific amounts of electromagnetic radiation, known as an emission spectrum. Each element emits a unique, identifiable, spectrum. Using the Bright-line emission spectrum chart below, identify the elements present in this modeled star (found in the line labeled “mixture”).
Lithium and cadmium are in the mixture. Strontium is not in the mixture.
Lithium and strontium are in the mixture. Cadmium is not in the mixture
Cadmium and strontium are in the mixture. Lithium is not in the mixture
All of the shown elements are present in the mixture.
