Graphite is a form of carbon. It contains nothing else.
Graphite is the most stable form of the already stable element carbon, and so will not decay at all.
graphite is a form of carbon that forms in layers which is why it is able to be used in pencils, because the layers can slide off and get left on the page. Anyway carbon is a non-metal so graphite is a non-metal.
Pencil lead is actually not lead (Pb) at all, but it is graphite. And graphite is simply carbons atoms. So, no, it is NOT a compound mixture.
Why? Because just about every substance that can be solid at all has a melting point, so it is not particularly surprising that graphite should have one.Note that some substances will change from solid directly to gas. That is called sublimation.
There are none, tungsten is a pure element so it is made of only tungsten.
Graphite is an element. It is a form of carbon.
None. Xenon is an element and so is not made up from any substances.

Graphite is composed of pure carbon, a non-metallic element. So there are no metals in graphite
Graphite is a form of Carbon, so its carbon in lead graphite. Notice that lead itself is a different element but the term "lead graphite" is generally used for that black substance which makes the "lead pencils". Note that there is no lead in lead pencils, its carbon, in the shape of graphite.

Bucky balls are a form (allotrope) of carbon, like graphite and diamonds. They are made of carbon, which is an element. They are a pure form of the element carbon, so they are an element.
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds
No, charcoal is considered a mixture with different substances in it, but if you have pure graphite, it is considered an allotrope of carbon (like diamond).
