Chapter 2 Flashcards
Pauli exclusion principle
Electrons can’t share all 4 quantum numbers
Aufbau principle
Fill orbitals from from lowest energy level to highest
Quantization
Atom cannot have any possible energy values; but instead limited to certain specific energy values
Heisenberg uncertainty principle
The position and velocity of an object cannot both be measured exactly, at the same time, even in theory
Hunds rule
Every orbital in a subshell is singly occupied with one electron before any one orbital id occupied
N, principle
Size/energy
L, angular
Shape
ml, magnetic
Orientation/ direction
Ms, spin
1/2; -1/2
Atomic radius
Decreases —> L to R
Increases —-> top to bottom
Ions
Anions are always larger than neutral atoms
Cations are always smaller than its neutral atom
Ionization energy
The amount of energy required to remove an electron from the nucleus
Zeffective
of protons - # of core electrons
Electron affinity (EA)
Energy change for the process of adding an electron to form an anion
Smallest to largest radius
F+, F, F-
