Identification
Used as a way to abbreviate electron configuration
Most of an atom’s mass and all of its positive charge are in the ______.
nucleus
T/F: Some atoms give off light when their electrons move from excited states down to lower states of energy.
False
____ _____ have full outer levels of electrons.
Noble gases
A graphic showing where all the electrons in an atom are located with all quantum numbers indicated
orbital diagram
The Greek symbol for frequency is ___, the symbol for wavelength is ___.
nu (ν) and lambda (λ)
What main energy level (n) would an electron be on if the energy level has 4 sublevels?
n = 4
This states that electrons occupy lowest energy levels before filling higher ones.
The aufbau principle
the number of waves that pass a given point in 1 second
frequency
T/F: In reference to an electromagnetic wave, when wavelength goes up, frequency goes down.
True
The third sublevel of a main energy level has _____ orbitals and can hold _____ electrons.
5, 10
This states that a maximum of two electrons can occupy a single orbital.
The Pauli exclusion principle
massless particles, each carrying a single quantum of energy
photons
T/F: Matter can only absorb energy in natural number increments of 1hv, 2hv, 3hv, etc.
True
Bohr is to orbits as Schrodinger is to _____.
orbitals
What is the electron configuration of sulfur (16) in noble gas notation?
[Ne] 3s² 3p⁴
The statement that every orbital within a sublevel gets an electron of the same spin before any orbital gets a second with opposing spin
Hund's rule
The speed (c) of electromagnetic waves in a vacuum
3.00 x 108 m/s
This states that it is fundamentally impossible to know both the precise location and velocity of a particle (like and electron) at the same time because you disturb it whenever you measure it.
The Heisenberg uncertainty principle
What is the orbital diagram of sulfur (16) ?
See paper.
