lesson 2 Flashcards
are arranged in regular, repeating patterns. They can only vibrate due to their limited space.
solid
flows easily, has medium attractive force.
liquid
can fly in all directions at great speeds.
gas
atoms lose electrons at very high temp. Nuclei and electrons mixed.
plasma
InterMolecular Forces of Attraction (IMFA)
FIRST (1st) statement
tiny particles that carry energy;
InterMolecular Forces of Attraction (IMFA)
SECOND (2nd) statement
interact with one another;
InterMolecular Forces of Attraction (IMFA)
THIRD (3rd) statement
are in constant random motion.
What are the different types of intermolecular forces?
intErmolecular forces and intrAmolecular forces
IntErmolecular forces
attractive forces present in between molecules.
IntrAmolecular forces
forces that hold atoms together.
which type of intermolecular forces is STRONGER?
Intramolecular forces are a lot stronger than Intermolecular forces
What are the four types of IntErmolecular forces?
1.) London Dispersion Forces
2.) Dipole-Dipole Forces
3.) Ion-Dipole Forces
4.) Hydrogen Bonding Forces
collectively known as Van der Waals’ forces of attraction, named after the Dutch Scientist Johannes Van der Waals.
1.) London Dispersion Forces
2.) Dipole-Dipole Forces
the weakest type of IMFA and is present in neutral molecules (polar or nonpolar)
London Dispersion Forces
moderately strong, can only occur between polar molecules
Dipole-Dipole Forces
