The Octet Rule

atoms tend to gain,lose,or share electrons until they are surrounded by eight valence electrons

Lattice Energy

the energy required to completely separate a mole of a solid ionic compound into its gaseous ions
for a given arrangement of ions, the lattice energy increases as the charges on the ions increase and as their radii decrease

Electronegativity

the ability of an atom in a molecule to attract electrons to itself

Lewis Structures

central atom is less electronegative than the atoms surrounding it

Formal Charge

valence- bonding/2-lone pairs

Bond Energy

energy required to break a bond

Covalent Bonds

atoms share e-, several electrostatic interactions, e- density shared equally

Dipole Moment

2 equal but opposite charges separated by distance. asymmetric charge distribution
