Term/Principle | Definition |
Pauli Exclusion Principle | No 2 electrons in the same element can have the same address. |
isoelectronic | When an ion has the same configuration as another pure element. |
Octet Rule | All elements desire to have a full outer shell( w/ 8 electrons) and will obtain electrons or get rid of them (whichever more convenient) to reach fullness. |
electronegativity | EN; msrmt. of the attraction for electrons |
ionization energy | amt. of energy needed to remove an electron |
atomic radius | nucleus to nucleus msrmt.

Periodic Law | the periodic table is organized by which ionization energy is the highest atomic number |
Aufbau Principle | electrons will go to lowest energy orbitals 1st |
quantum numbers:
2 | Principal Q. #; energy levels |
quantum numbers:
s | Angular Momentum Q. #; shape of orbital; sublevels, blocks |
quantum numbers:
x, y, z or -1, 0, 1 | Magnetic Q#; orientation(how the orbitals sit) |
Heisenberg Uncertainty Principle | We never w/ certainty know the exact location of an electron. |
Hund's Rule | Electrons must be placed one at a time in p, d, and f blocks before you double up. |
Explain levels of EN, AR, and IE on periodic table. | As Atomic radius decreases(left to right), Electronegativity and Ionization energy increase. |
