Chemistry Bonding Part 3

675108675	polar covalent	(12.1) Bonding in which the atoms are not so different that electrons are completely transferred but are different enough so that unequal sharing of electrons results (a bond forms in which electrons are shared unequally).
675108676	resonance	(12.7) When more the 1 Lewis structure can be drawn for the molecule.
675108677	resonance structure	(12.7) The various Lewis structures for a molecule.
675108678	single bond	(12.7) One electron pair are shared.
675108679	tetrahedral structure	(12.8) Four pairs of electrons on a central atom in a molecule are always placed 109.5o apart.
675108680	trigonal planar structure	(12.8) Three pairs of electrons on a central atom in a molecule are always placed 120o apart in the same plane as the central atom.
675108681	trigonal pyramid	(12.9) The molecule electron pairs have a tetrahedral arrangement but not a tetrahedral arrangement of atoms (one side is different from the other 3 sides; the structure is a pyramid with a triangle as a base.).
675108682	triple bond	(12.7) Three electron pairs are shared.
675108683	valance shell electron pair repulsion (VSEPR) model	(12.9) This model purpose is that the structure around a give atom is determined by minimizing repulsions between electron pairs. It's useful for predicting the molecular structures of molecules formed from non-metals.
