13. When an electron in an atom jumps from a higher energy level to a lower one: A. Energy is absorbed C. The atom splits B. energy is emitted D. Nothing happens

## Step 1<br />When an electron in an atom jumps from a higher energy level to a lower one, it is said to de-excite. This process involves the release of energy.<br /><br />## Step 2<br />The energy released during this process is emitted in the form of a photon. This photon is a packet of light energy.<br /><br />## Step 3<br />This phenomenon is the basis for the emission spectrum of elements. Each element has a unique set of energy levels, and when an electron jumps between these levels, it emits energy at specific wavelengths. This is what creates the unique lines seen in the emission spectrum of each element.
