Intra/intermolecular forces Flashcards
An idea that matter is composed of tiny particles that are always in motion.
Kinetic Molecular Theory
Postulates of
Kinetic Molecular Theory

kinetic Energy
Postulates of
Kinetic Molecular Theory
The amount of kinetic energy in a substance is related to its _____. Increased in _____ means _________.
temperature, greater speed
Postulates of
Kinetic Molecular Theory
_____ changes happen when the _____ of the substance changes sufficiently.
phase, temperature
Postulates of
Kinetic Molecular Theory
There are attractive forces in between particles called ________. The strength of these particles increases as particles get closer together.
intermolecular forces
5 postulates of kinetic molecular theory
kinetic energy, temp, space, phases, intermolecular forces
two kinds of forces/attractions
intramolecular & intermolecular
(within molecules) force that hold the atom together in a molecule
intramolecular
1.
force that stabilize each other
intramolecular
force happen between molecules
intermolecular
Formed between atoms with similar electronegativities-the affinity or desire for electrons.
covalent bond
2 types of intramolecular force
ionic & covalent bond
what is the electronegativity of ionic bond
greater than 2.0
2 types of covalent bond
polar & non-polar bond
Formed between same atoms or atoms with very similar electronegativities.
non-polar bond
