metallic bonding and nanoparticles Flashcards
1
Q
what do metals consist of?
A
a giant structure
2
Q
characteristics of metals’ giant structure
A
strong forces of attraction, regular structure, conducts electricity
3
Q
what are nanoparticles
A
particles with a diameter between 1nm and 100nm
4
Q
properties of nanoparticles
A
high surface area: volume ratio, meaning that properties of materials can be different depending on whether it’s a nanoparticle or if it’s in bulk
5
Q
uses of nanoparticles
A
making new catalysts, delivering drugs straight to the cells where they’re needed, electrical circuits, cosmetics
6
Q
downsides of nanoparticles
A
the way they effect the body isn’t fully understood, people are worried that products with nanoparticles in have been made available too soon and we don’t know what their impacts are
