675108675polar 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).
675108676resonance(12.7) When more the 1 Lewis structure can be drawn for the molecule.
675108677resonance structure(12.7) The various Lewis structures for a molecule.
675108678single bond(12.7) One electron pair are shared.
675108679tetrahedral structure(12.8) Four pairs of electrons on a central atom in a molecule are always placed 109.5o apart.
675108680trigonal 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.
675108681trigonal 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.).
675108682triple bond(12.7) Three electron pairs are shared.
675108683valance 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.

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
