•    jumps from a lower to a higher energy level.   
•    moves within its atomic orbital.
• falls into the nucleus.

Why are line emission spectra of elements called "atomic fingerprints"?

• They are all the same
• They are all unique
• They are all similar
• They all contain colored light

What do spectroscopes do?

• Collect light to identify elements

• Refract light

• Absorb light

• Transmit light

When sunlight is split by a prism or diffraction grating it appears to emit a ___ spectra.

• absorption

• dark-line

• continuous

• bright-line
