Covalent Bonds:
-Electrons shared between non-metals.
-To draw lewis dot diagrams:
1.)Total all valence e- in all atoms.
2.)Identify the element that can form the most bonds. Thie will be the central atom.
3.)Draw bonds netween atoms as a -------. This represents 2e-.
4.)Any e- not part of a bond are lone pairs around the atom.
5.)Check to make sure each atom has a full octet.
