What are Transition Metals used for?
Catalysts
Give the distinctive properties of Transition Metals compounds
Form ions with different charges and coloured compounds
What is the difference between the charges of Transition Metals ions and Group 1 ions?
Transition Metals can form different charges/Group 1 metals can only form 1+ ions
How big are nanoparticles?
1-100nm
How are nanomaterials different from bulk materials?
Nanomaterials have a much higher surface area to volume ratio
What is the relationship between side length and surface area to volume ratio?
As side length decreases by a factor of ten, the surface area to volume ratio increases by a scale factor of ten
What are nanoparticles used for?
Used in healthcare, electronics, cosmetics, and catalysts
How big are fine particles?
100-2500 nm
How big are coarse particles?
2.5x10^-6 to 1x10^-5 m
