Arrhenius
Acid ionized in water to produce protons and a base produces hydroxide ions.
Sigma Bond
Bond in which the orbitals overlap along a line connecting the atoms.
Hund's Rule
Each orbital is single occupied before any one is double occupied.
Structure vs. Acidity
-Strength of the bond to the atom from which the proton is lost.
-The electronegativity of the atom from which the proton is lost.
-Changes in electron delocalization on ionization.
Heisenberg Uncertainty Principle
-We can't tell exactly where an electron is but we can tell where it is most likely to be.
Boundary Surfaces
Enclose the region where the probability of finding an electron is on the order of 90-95%.
Inductive Effects
Electronic effect transmitted by succesive polarization of the sigma bonds within a molecule or an ion.
Ionization Energy
Amount of energy needed for an atom to lose one of its electrons.
Stronger Acid + Stronger Base >>>>>>>>Weaker Acid + Weaker Base
The reaction is favorable when the stronger acid is on the left and the weaker acid is on the right.
Dipole
Centers of positive and negative charge that are separated from each other.
Electron Affinity
Energy caused by the addition of an electron to an atom.
Pauli Exclusion Principle
Two electrons may occupy the same orbital only when they have opposite or paired spins.
Principal Quamtum Number
Specifies the shell, is denoted by the period or row of the periodic table.
Electrophiles
Lewis Acids
Nucleophiles
Lewis' Bases
