What is the atomic emission spectrum?

• The pattern formed when light emitted by an element is separated into the different wavelengths it contains.

• The specific frequencies of light emitted by an element.

• The tool that uses a prism to separate light into its individual colors.

• The fixed energies an electron can have in an atom.

What is the purpose of a spectroscope?

• To emit light of specific wavelengths.

• To absorb energy in a gaseous state.

• To separate light into its individual colors.

• To identify unknown samples.

Why is the atomic emission spectrum considered like a fingerprint for each element?

• Because it can be used to identify unknown samples.

• Because it contains specific wavelengths of light.

• Because it is unique to each element.

• Because it is the same for atoms anywhere in the universe.

What is a quantum of energy in the context of the Bohr model?

• The energy required to move an electron from one energy level to another.

• The specific amount of energy gained or lost by an electron in an atom.

• The size of a step in climbing stairs.

• The energy difference between any two energy levels in an atom.

Why do hydrogen atoms emit specific wavelengths of light according to the Bohr model?

• Because the energy levels in hydrogen atoms are equally spaced.

• Because the energy levels in hydrogen atoms are not equally spaced.

• Because electrons in hydrogen atoms move in circular paths.

• Because hydrogen atoms have a unique atomic emission spectrum.
