Emission Spectra

What does the Bohr model suggest about the energy of electrons in an atom?

• It is continuous

• It is quantized

• It fluctuates constantly

• It is only present at high temperatures

What is an emission spectrum?

• A continuous spectrum of light

• A spectrum that shows specific bright lines

• A spectrum that is the same for all elements

• A spectrum that cannot be observed

What does the term "line spectrum" refer to?

• A spectrum with no visible lines

• A spectrum with continuous colors

• A spectrum with specific bright lines and dark spaces

• A spectrum that varies with temperature

According to the Bohr model, what happens when an electron jumps from a lower orbit to a higher orbit?

• It loses energy

• It absorbs energy

• It becomes unstable

• It emits light

What type of light is emitted when electrons transition from higher to lower energy orbits?

• Only infrared light

• Only ultraviolet light

• Visible light

• No light is emitted
