LM13-14 Flashcards
Noble Gas Notation
Usage of noble gases (i.e. [Ne]) to shorten completely filled periods in electron configuration
Pauli Exclusion emphasis
Two electrons per orbital
Hund’s Rule emphasis
Distribute electrons amongst degenerate energy levels (applies to d and p)
Degenerate energy levels
Equal energy levels that occur in the same subshells with different orientations
Aufbau Principle emphasis
Sequence of electron orbitals by distance from nucleus
Isoelectronic
Equal in the number of electrons
Ions are equivalent to their _____ counterparts
Neutral atom
Paramagnetism
Unpaired electrons present in an atom that result in magnetic properties
Diamagnetism
All electrons are paired
Ionization Energy
Energy required to remove an electron
Electron Affinity
Ability of an atom to attract an electron
Opposite charges will
attract
Like charges will
repel
Most trends follow an arrow on the periodic table going from
Lower left to upper right
Properties that are higher on the lower left
Metallicness, radius
Shielding
The repelling of electrons away from the nucleus in ascending groups
Effective Nuclear Charge (ENC)
Attraction of protons in the nucleus to electrons, considering weakened attractions by shielding
ENC formula
of protons - # of shielding inner-shell electrons
Moving right in the same period does what to ENC and radius?
More ENC, less size
Paramagnetism or Diamagnetism would be based off what electron subshell?
The last that came in the electron configuration, NOT the highest shell
