This force keeps molecules together
intermolecular attraction
The particle of this matter has complete freedom of motion
gas
The particle of this matter has essentially in fixed position
Solid
The particle of this matter is free to move relative to each other
Liquid
What is the fundamental difference of particles between the state of matter
mass
Solid and liquid states particles are closer together, we refer them as _____
Condensed
What is the density of solid
very high
What is the diffusability of liquid
Slow
Particles of this matter are able to slide past one another
Liquid
This matter assumes the shape of the container it occupies
Liquid
The bonding of electrons shared equally between atoms
Non-polar covalent bond
The tendency of an electron cloud to destort
Polarizability Bond
In this force, molecules that have permanent dipoles are attracted to each other
Dipole-dipole
Bonding of electrons shared unequally between atoms
Polar covalent bond
The more polar the molecule, the higher the _____
Boiling point
Force when hydrogen is bonded to one of those very electronegative elements
Hydrogen bonding
Force of attractions between an instantaneous dipole and an induced dipole
London dispersion
The strength of these forces is what make it possible for ionic substances to dissolve in polar solvents.
Ion dipole
The normal boiling point is the temperature at which its vapor pressure is _____
760 torr
Gaseous state of a substance which is normally liquid or solid at room temperature
Vapor
Types of intermolecular force
Hydrogen bonding, Dipole-dipole, London dispersion, Ion dipole
Subatomic particles
protons, neutrons and electrons.
Elements that can bond with hydrogen in hydrogen bonding
Oxygen, Nitrogen, Fluorine
