1.3 - Atomic Emission Spectra and the Bohr Model(Gen Ed)

What happens when an element absorbs energy in a gaseous state?

• The electrons become excited and the atom emits light.

• The atom becomes stable and stops emitting light.

• The electrons lose energy and the atom absorbs light.

• The atom releases energy and becomes solid.

What is an atomic emission spectrum?

• A pattern formed when light emitted by an element is separated into different wavelengths.

• A continuous spectrum of all colors and visible wavelengths.

• A tool used to measure the temperature of an element.

• A method to increase the energy of an atom.

What does a spectroscope do?

• It separates light into its individual colors.

• It combines different colors into white light.

• It measures the temperature of light.

• It increases the energy of light.

What is the atomic emission spectrum of an element compared to?

• A person's fingerprint

• A person's DNA

• A person's eye color

• A person's voice

What can atomic emission spectra be used to identify?

• Unknown samples

• Chemical reactions

• Physical states

• Temperature changes

What does each spectral line in an atomic emission spectrum correspond to?

• One wavelength of visible light

• One type of chemical bond

• One electron orbit

• One type of atom

What are the fixed energies an electron can have in an atom called?

• Quantum levels

What must an electron do to move from one energy level to another?

• Gain or lose any amount of energy

• Gain or lose just the right amount of energy

• Remain at the same energy level
