Ø Electrostatic forces. Opposite charges attract each other. o These are the strongest intermolecular forces. Hold many ions in a crystal lattice structure.

2
covalent bonding
o Nonpolar bonding with an equal sharing of electrons. o Polar bonding with an unequal sharing of electrons.
New cards
3
electrostatic attraction
the attraction between positive and negative charges
New cards
4
intramolecular forces
are the forces within a molecule (e.g., ionic, covalent, polar covalent, metallic).
New cards
5
intermolecular forces
are forces between different molecules (e.g., atoms or ions).
New cards
6
dipole-dipole forces
forces of attraction between polar molecules
New cards
7
ion-dipole forces
attractive forces between an ion and a polar molecule
New cards
8
permanent dipole
Molecules are attracted to each other in a compound by these positive and negative forces
New cards
9
hydrogen bonding
the intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule
New cards
10
london dispersion forces
is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles
New cards
11
instantaneous dipole
temporary dipole that occurs for a brief moment in time when the electrons of an atom or molecule are distributed asymmetrically
New cards
12
van der waals forces
a slight attraction that develops between the oppositely charged regions of nearby molecules
