Cards (9)

What is the ionic structure called
giant lattice
Simple Molecular Substances points
Joined by covalent bonds
Weak intermolecular forces
Low boiling/melting point
What are fullerenes
molecules of carbon shaped like a closed tube or hollow ball
Propteries of fullernes
high surface area
good catalysts
great lubricants.
What are nanotubes
tiny carbon cylinders made from fullerenes
nanotube properties
conductive
high tensile strength
used in electronics or to strengthen materials
What are allotropes
different structural forms of the same element in the same physical state.
How big are nanoparticles
1-100nm
Properties and uses of nanoparticles
high surface area to volume ratio
Used to:
deliver drugs
electric circuits
suncream/cosmetics
