33
Photoelectric Effect
electron is released from material's surface when bombarded w/ electromagnetic radiation such as light
34
Albert Einstein
Photoelectric Effect
35
Wave Particle Duality
Particle can be wave and particle
36
demonstrated photoelectric effect
Robert Millikan
37
photon
light behaving as particle
38
Photoelectron
ejected electron
39
Threshold Frequency
the lowest frequency of a light/ electromagnetic rad that can cause photoelectric effect
40
de broglie's wavelength
wave properties of matter
41
Principal shells and subshell
dictates how the e- are distributed among the various orbitals
42
Pauli's Exclusion Principle
No two e- can have the same set of quantum numbers due to spin quantum number
43
Wolfgang Pauli
Pauli's Exclusion Principle
44
Hund's Rule
e- initially occupy these orbitals singly and with parallel spins.
Friedrich Hund
45
Shielding
e- close to the nucleus shield outer e- from the nucleus
46
Penetration
e- that can get close to the nucleus. Good screeners
47
Aufbau Principle
AKA Building up principle.
Assign e- config to the elements in the order of increasing atomic number
48
Heisenberg Uncertainty Principle
states the momentum and location can be determined one at a time but not at the same timemp
49
Compton Effect
when a photon collides with an electron, it transfers momentum to the e- which accelerates it to a new velocity
energy photon inversely proportional to wavelength
50
Argon
element constituted the need of a new group in the original design of Dmitri Mendeleev’s Periodic Table
50
Diamagnetic
all of its e- are paired
51
Paramagnetic
at least one is unpaired
52
Intramolecular
bonds that holds atom together
53
53
Intermolecular Forces
bonds between molecules
54
Instantaneous Dipole
separation of charges in a non-polar molecule at an instant due to sudden disturbance in the electric cloud around the molecule
55
Polarizability
the tendency of a molecule to acquire an electric dipole moment when subjected to an electric field
56
CH3CHOHCH3
isopropyl alcohol
57
Law of Conservation of Energy
energy can be converted from one form to another
58
Internal Energy
Summation of the KE and PE of the particles
59
Energy in Transit
can only exist while being transferred from one system to the next
60
Ludwig Boltzmann
explained concept of entropy, after 27 it was introduced
61
positive change in entropy
A process wherein two ideal gases in separate bulbs, both at a pressure of 1 bar, are connected and allowed to expand into the total volume
62
Microstates
specific microscopic config describing how the particles of system are distributed
