Chemical Bonding

Valence Electrons Valence electrons are found in the incomplete outermost shell of an atom.

The Octet Rule Atoms tend to gain, lose or share electrons until they are surrounded by eight valence electrons.

Pre – AP Physical Science Bond Types

Ionic Bonding One or more electrons from one atom are transferred to another atom, and the resulting positive or negative ion then attract each other

Covalent Bonding Two adjacent atoms share one or more pairs of electrons. The electrons spend more time between the two atoms than anywhere else.
