metals are elements which can form positive ions when they react
what are non-metals?
elements that don't generally form positive ions when they react
how do atoms form a full outer shell?
by gaining, losing or sharingelectrons
why is it easier for metals to form ions?
as they don't have to remove many electrons and metals towards the bottom the periodic table have an outer shell that is further away from the nucleus which means electrons will have a weaker attraction.
what are the properties of metals?
they are strong but can be bent or hammered into a shape (malleable)
great conductors of heat and electricity
high melting and boiling points
what are the properties of non-metals?
brittle
aren't always solid at room temperature
poor conductors of heat and electricity
lower density
where can transition metals be found?
found in the centre of the periodic table between group2 and 3
what are the special properties of transition metals?
