Question
What does the emission spectrum of a molecule show?A.The energy the molecule absorbs as it undergoes a reaction to break down into its elementsB.The wavelengths of light a molecule takes in when an electron moves to a higher energy levelC.The wavelengths of light a molecule gives off when an electron moves to lower energy levelsD.The energy the elements give off as they undergo a reaction to form a molecule
Solution
The emission spectrum of a molecule shows C. The wavelengths of light a molecule gives off when an electron moves to lower energy levels.
Here's a step-by-step explanation:
-
When a molecule absorbs energy, its electrons can move to a higher energy level, or an "excited state."
-
Eventually, these excited electrons will return to their original, or "ground," state.
-
As they return to the ground state, the electrons will release the energy they previously absorbed.
-
This energy is released in the form of light. The color (or wavelength) of this light corresponds to
