Unit 6: IMFS

Melting

The state change from Solid to Liquid

Freezing

The state change from Liquid to Solid

Sublimation

The state change from Solid to Gas

Deposition

The state change from Gas to Solid

Evaporation

Condensation

The state change from Gas to Liquid

Hydrogen Bonding

The strongest intermolecular force that results from the electronegativity difference that occurs when Hydrogen is bonded to Nitrogen, Oxygen, or Fluorine

Dipole-Dipole Interactions

The interaction between partial charges in a molecular due to the presence of a polar covalent bond

London Dispersion Forces

The weakest intermolecular force; the temporary attraction between molecules due to electron movement

Polar Covalent Bond

A bond between two nonmetals that has an electronegativity difference between 0.4 and 1.7. In this bond, there is an unequal sharing of electrons.

Ionic Bond

The bond type occurs between metals and nonmetals. This type of bonding involves the complete transfer of electron(s) from one atom to another. This bond type has an electronegativity difference greater than 1.7.

Nonpolar Covalent Bond

A bond between two nonmetals that has an electronegativity difference less than 0.4. In this bond, there is an equal sharing of electrons.

Electronegativity

The ability of an atom to attract electrons when the atom is in a compound. How much the atom "hogs" electrons

Potential Energy

The energy between particles. The farther part they are, the more of this they have.

Kinetic Energy

The energy of motion, helps us to figure out how fast the molecules are moving and what state they might be in

Intermolecular Forces

The forces BETWEEN molecules. Examples include Hydrogen Bonding, Dipole Dipole Attractions, and London Dispersion Forces.

Intramolecular Forces

The forces between atoms INSIDE the molecule. Examples include polar and nonpolar bonds.
