VSEPR - Valence shell electron repulsion: place the electron around the central atom as far from each other as possible Electron-group arrangement - The 3-D geometric shape that the bonding and nonbonding electron occupy Molecular shape - The 3D shape that only the bonded atoms occupy, i.e. What the molecule "looks like" AXmEn notation - A=central atom

Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...
