VDWF Flashcards
What condenses at sufficiently low temperatures
Molecules
Monoatomic elements
Compounds
For MMC to freeze at sufficiently low temperatures what needs to occur?
Some forces of attraction must exist between molecules or discrete atoms
What is the term for forces of attractions
VAN DER WAALS FORCES
what are VDWF
intermolecular forces that hold *molecules, ions and particles within compounds.
What are LDF
forces of attraction and hat can operate between all atoms and molecules
They are much weaker then any other types of bonding
How are LDF formed
They are formed as a result of electrostatic attraction between temporary dipoles & induced dipoles, caused by movement of electrons in atoms & molecules
What does the strength of LFD equavlent to
No of E within atom or molecule
