SECTION 2-1 CONT.
Bonding
TYPES OF CHEMICAL BONDS
Bonds involve the electrons in an atom.
1. Ionic Bonds• Electrons are transferred from one
atom to another• Formed from ions with a similar
opposite charge• Ex: Mg2+ and O2-
TYPES OF CHEMICAL BONDS
2. Covalent Bonds• Electrons are shared between
the atoms• Not always shared equally
TYPES OF CHEMICAL BONDS
3. Van der Waals Forces
(Intermolecular)• Unequal sharing of electrons
can create regions of a molecule that are charged. • These charged areas are
attracted to regions on a nearby molecule with an opposite charge.
