Transition metals and nanoparticles Flashcards
1
Q
What are the properties of the transition metals?
A
- Melting point is relatively high
- Density is relatively high
- Strength of transition metals is relatively high
- Hardness is relatively hard
- Reactivity with oxygen, water and Halogens react very slowly
2
Q
What are transition metals very useful for?
A
Transition metals are very useful Catalyst so they increase the rate of a reaciton without being used up.
3
Q
What do Transition metals often form as compounds?
A
Often become a different colour.
4
Q

5
Q
What are the uses of nanoparticles?
A
- Healthcare
- Electronics
- Cosmetics
- Catalysts
