Ch 6

Question 0

Paramagnetic

Answer 0

More than 1 unpaired e-

Question 1

Stern Gerlach experiment

Answer 1

Discovered m_s from 2 steams of atoms - aligned with or opposed mag field

Question 2

Diamagnetic was exposed to b field

Answer 2

Slight repulsion

Question 3

m_s

Answer 3

Electron spin number, +/- 1/2

Question 4

Einstein

Answer 4

Light has wave and particle properties, can be thought of as a stream of tiny packets of energy (photons)

Question 5

Planck’s equation

Answer 5

E=hv

Question 6

Planck

Answer 6

Energy is quantized

Question 7

Photoelectric effect

Answer 7

Einstein, e- ejected when light struck surface of metal, but only if frequency was high enough, regardless of light intensity (brightness)

Question 8

Condition to eject e- from metal using light

Answer 8

Frequency (energy of each photon) must be high enough to dislodge an e-. Brightness or light intensity (amount of photons) can increase the # e- dislodged, but doesn’t affect threshold energy.
