Chemistry Unit 3 - Sections 8.1-8.3 (Types of Chemical Bonds, Electronegativity, Bond Polarity, and Dipole Moments)

Bonds are:

Forces that hold groups of atoms together so they can function as a unit

Bond Energy:

Amount of energy required to break a bond.

Ionic Bonds

Two oppositely charged ions held trogether via electrostatic forces

Ionic bonds typically form when:

One atom that easily loses electrons is near another with a high electron affinity.

What is Coulomb's Law:

E=kQ1Q2/R

Covalent Bonds

Electrons are shared between two atoms

Nonpolar Covalent:

Equal sharing of electrons

Polar Covalent

One atom exerts greater attraction electrons

Dipole Moment

Molecule has a center of positive charge and a center of negative charge
