•    jumps from a lower to a higher energy level.   
•    moves within its atomic orbital.
• falls into the nucleus.

Which drawing represents the process by which an absorption line is formed?

• A

• C
• D

The ground state is the ______________ energy state of an atom.

• highest

For an electron to change from ground state to an excited stated it must...

• Absorb energy
• Release energy

When talking about energy levels in an atom, what is an "excited state"?

• The highest energy state of an atom.
• Any level higher than the ground state.
• The lowest energy state of an atom.
• When an atom loses an electron

Why are line emission spectra of elements called "atomic fingerprints"?

• They are all the same
• They are all unique
• They are all similar
• They all contain colored light

An emission spectrum is produced when an electron moves from one energy level
