|
|
how many quantum numbers are needed to completely describe an electron?
|
4
|
|
|
Hund's rule
|
orbitals of equal energy are occupied by one electron before any orbital has two.
|
|
|
Aufbau's Principle
|
An electron occupies the lowest energy orbital that can recieve it
|
|
|
Pauli's Exclusion Principle
|
No two electrons in the same atom can have the same set of quantum #'s
If two electrons are in the same level, sublevel and orbital, they must have opposite spins |
|

10
|
|
|
how many total electrons can be found in energy level 4?

list electromagnetic spectrum and label in order according to wavelengths, frequencies and energies.
|
Radio, tv, radar, micro, infrared, visible, uv, xray, gamma; longest wavelength to shortest; lowest energy to highest; lowest frequency to highest
|
|
|
describe what is meant by dual nature of light
|
light behaves like a wave and a particle
|
|
|
who came up the photon and what does it mean?
|

|
|
|
What happens to an electron when it absorbs a quantum of energy?
|
it goes to the excited state, then moves up an orbital
|
|
|
what does heisenberg's uncertainty principle mean compared to bohr's model?

whose formula predicts the complex shapes of the orbital's in the quantum model of an atom?
|
schrodinger
|
|
|
which type of electron configurationshows electrons as arrows?
|
orbital notation
|
|
