The electron moves from position 1 to 2. How does the state of the electron shift during this reaction?

• The electron becomes less excited.

• The electron returns to the ground state.

• The electron becomes more excited.

• Light is emitted

What is an atomic emission spectrum?

• a diagram that shows the energies of molecular orbitals

• a spectrum that contains radiation distributed over all wavelengths

• the arrangement of electrons in the orbitals of an atom or molecule

• a series of colored lines that correspond to photons of specific energies emitted by a heated element

Each line in an atomic emission spectrum corresponds to:

• an exact amount of energy being given off by the atom

• one exact frequency of light being absorbed by the atom

• the number of electrons emitted in an atom

• the number of protons absorbed in an atom
