Light Emission And Absorption

The _______________ determines the color of visible light. 

• wavelength
• speed
• amplitude
• light

Emission of light from an atom occurs when an electron

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

For an electron to change from ground state to an excited stated it must...

• Absorb energy
• Release energy

When talking about energy levels in an atom, what is an "excited state"?

• The highest energy state of an atom.
• Any level higher than the ground state.
• The lowest energy state of an atom.
• When an atom loses an electron

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

A line spectrum is produced when an electron moves from one energy level

• into the nucleus

• to a higher energy level

• to another position in the same sublevel

• to a lower energy level

Emission spectra emitted by an element (or compound) will produce ___ through a spectroscope.

• bright lines

• a continuous rainbow

• dark lines

• white light

The lowest energy configurations for electrons in an atom is called the

• neutral state

• home state

• ground state

• base state

The hydrogen cloud would....

• absorb energy from the source
• emit energy from the source
• be irrelevant
• decrease the frequency of the photons

What is the light that you can see called?

• observatory light

• ultraviolet light

• visible light

• infrared light
