Chemistry 15 Flashcards
VSEPR Theory
Electron pairs in the valence shell stay as far apart as possible allowing prediction of molecular shapes.
Resonance Structure
Different arrangements of electrons of the compound having a geometrical structure.
Unshared Pair
A non-bonding pair of electrons.
Lewis Structure
Diagram using dots to represent electrons.
Valence Electrons
Number of electrons in the outermost energy level.
Dipole
Molocule with both a positive and negative region.
Covelent Bonds
When atoms share one or more pairs of electrons.
Molecular Orbital
The probable region of an electrons location around a molecule.
Polar Compound
A molecule where the shared electrons are held more closely by one atom yielding a positive and negative end.
Ionic Bond
The bond between a cation and an anion to form a compund.
Hydrogen Bond
Intermolecular attraction between a H of a molecule and a charged region.
Double Bond
Two atoms that share four electrons.
