What happens to elements in a group the further down the table they are?
The properties start to change and they become more reactive.
What are properties of alkali metals?
They are all soft, shiny, and highly reactive
What are properties of halogens?
They can be solid, liquid, or gas, and are reactive non-metals
What are properties of noble gasses?
They are unreactive non-metals
What are properties of transition metals
They are hard, dense, and less reactive than alkali metals
What does density mean?
There are more atoms per area.
The particles are tighter packed
What does malleability mean?
Can bend and change shape.
What does reactivity? mean
A measure of how easily an element forms compounds
What does ductile mean?
It can be stretched easily
What does electrical conductor mean?
Electricity can flow through it
What does strength measure?
How well an object withstands force applied to it.
What does alloy mean
A mixture containing at least 2 elements and at least 1 metal (must be mainly metal)
Name the non metal that can conduct electricity and the form that it can conduct electricity in.
Carbon in the form of graphite
