Key Concepts
Ionic Bonds-Molecules that have an ionic bond can't share atoms. They are transferred.
-Ionic bonding involves electrostatic attraction between two opposite charged atoms.
-Ionic bonds do not form molecules. They create formula units which are the smallest ratios in whole numbers of th proportions of the atoms in ionic compounds.
|
Covalent Bonds-Molecules that have covalent bonds share atoms.
-A covalent bond is a force that holds atoms together. (This happens when they share electrons.)
-There are two types of covalent bonds: Polar Covalent Bonds and Non-polar Covalent Bonds.
