Review
What is the octet rule?
Covalent Bonds
Rather than giving away or accepting electrons, some atoms share their outer electrons to achieve full outer shells.
Covalent boding is where two or more non-metal atoms share pairs of valence electrons. Covalent bonding may be single or multiple, depending on the number of pairs the atoms share.
What kind of bond is the compound CH4 held together by?
Explain.
Sharing Electrons
Covalent bonds are formed from pairs of electrons, one from each atom. The pair is included in the outer shell of both atoms at once.







This allows both atoms have a full set of 8 electrons in their outer shell and become stable. No electrons leave their original atoms -- so the atoms always remain neutral.
