-
-
-
-
SIMILARITIES AS METALS
they are hard, tough and strong
-
-
OTHER SIMILARITIES
-
they can form ions with different charges (aka they have variable valency)
- the different oxidation states lead to the different colors of compound.
-
USING IRON AS AN EXAMPLE
- is strong enough to be used in building bridges
- has nearly 8 times the density of water
- melts at 1535 degrees celcius.
-
iron can form Fe^2+ and Fe^3+ ions.
- The name of the iron compound tells you which ion is in it:
- iron(II) oxide contains Fe^2+ ions
- iron(III) oxide contains Fe^3+ ions.
