What is the Bohr model?

A theory that describes the structure of atoms, where electrons orbit the nucleus in defined paths or energy levels.

A model that explains the behavior of gases under pressure.

A theory that states all matter is made up of tiny particles called atoms.

What is the difference between emission and absorption spectra?

Emission spectra show the wavelengths of light absorbed by an atom, while absorption spectra show the wavelengths of light emitted by an atom.

Emission spectra show the wavelengths of light emitted by an atom, while absorption spectra show the wavelengths of light absorbed by an atom.

Emission spectra and absorption spectra are the same and show no difference in wavelengths.

Emission spectra are produced by molecules, while absorption spectra are produced by solids.

What is ground state?

The highest energy state of an atom, where electrons are farthest from the nucleus.

The lowest energy state of an atom, where electrons are in their closest orbits to the nucleus.

A state of an atom where electrons are in random orbits around the nucleus.

The state of an atom when it is ionized and has lost one or more electrons.

What is the role of energy levels in emission spectra?

Energy levels determine the specific wavelengths of light emitted when electrons transition between them.

Energy levels are irrelevant to emission spectra.

Energy levels only affect the color of light emitted.

Energy levels are constant and do not change during electron transitions.
