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”).

Which element(s) is/are found in the star's spectra below?

If an electron moves from n=4 to n=2 it ____

Look carefully at the picture. It shows an electron in the excited state on the left, and the electron returning to its ground state on the right. When the electron return to the ground state it emits a_______________________.

The picture shows an atom in the ground state absorbing energy and the electron jumps to the excited state. Which state has higher energy?

Each element produces its own pattern of emission spectra lines because each element has its own distinct
