Compare transition metals to group 1 elements
Transition metals : - Harder and stronger - Higher melting points (except mercury) - Higher densities - Much less reactive, do not react vigorously with oxygen or water

Hard Very brittle Difficult to fuse Easy to oxidise
Iron properties?
Good conductor Rusts in air Strong Ductile Malleable
Cobal properties?
Hard Brittle High melting point
Nickel properties
Malleable Hard Ductile Good conductor of heat and electricity
Copper properties
Malleable Soft Highly ductile and conductive
