Answer 1

An electron in an atom absorbs a photon, moves to a higher energy excited state, then emits energy as it returns to ground state, producing an emission spectrum. This process helps identify elements in distant stars by comparing their emission spectra to known elements on Earth.

Step-by-step explanation:

When an electron absorbs energy, it jumps to a higher energy level, moving from the ground state to an excited state. This absorbs a photon of energy. When the electron returns to its ground state, it emits energy in the form of a photon, producing an emission spectrum. The energy released from an excited electron is equal to the energy that was absorbed. Astronomers use this principle to identify elements in distant stars by comparing the emission spectra to those of known elements on Earth.

Thus, the unscrambled and rewritten sentences are:

When an electron is excited, it will jump up to a higher energy level, absorbing a photon that makes it absorb energy. The energy levels that electrons can occupy in an atom are quantized. When the electron returns to the ground state, it releases energy in the form of a photon; this process is observed on Earth as a bright-line emission spectrum. The energy released from an excited electron is equal to the energy of the absorbed photon. By fusing together the emission spectra of distant stars, we can compare the elements found in stars to the known elements' spectrum.
