Why do atoms form bonds? To attain a noble gas configuration. How do atoms form bonds? By gaining, losing, or sharing electrons. Gain or loss of electrons ionic bonding Sharing of electrons covalent bonding
Covalent Bonding Results from the attraction between the nucleus on one atom and the electrons on another atom.
The electrons are shared, but not transferred. Often formed between 2 nonmetal atoms of the same element. If Attractions are greater than Repulsions, a bond is formed.
Potential Energy vs. Internuclear Distance Low energy High stability Bonding Systems Non-Bonding Systems
Different ways of representing a covalent bond. Compounds with covalent bonds are molecular!
