ch 6 spectrum and x ray 1

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

• Absorb energy
• Release energy

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.

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

The type of spectrum generated here is called...

• absoption
• continuous
• constant
• emission

There is an emission spectrum and absoption spectrum shown here. What is the bottom spectrum?

• an emission spectrum
• an absoption spectrum
• neither
• both

• Balmer series

• paschen series

• no correct answer

Which series of hydrogen emission spectrum lines has frequencies that fall in the range of ultraviolet?

• Lyman series

• Balmer series

• all of the above

Electrons drop from higher energy level to energy level ____ in Paschen series

• 1

• 2

• 3

• 4

n=1 to n=2 energy level gap is shown by which line in which series of the Hydrogen spectrum?

• Lyman series lowest frequency line

• Balmer series lowest frequency line
