what are the physical and chamical properties of carbon?

Question

if you answer i'll give you 10 points...whoever is reading this

sorry that's chemical instead of chamical, thanks...if you know the answer, don't put it in really complicated writing, i'm only in year 8

Look! It is reactive, it reacts easily. It is dull, brittle, etc. Brittle means it is broken when you bow it, not twisted!
It is a substance in organic (living) things. Unlike most non-metals, it conducts electricity when graphite.

Conducting electricity is to let electricity move in it. You are 8 you said, so it would be some complicated to enter more in electric conductivity.

Graphite is what is grey in your pencil. It is made from carbon!

Carbon's density ,or amount of carbon in a special size ,is 2.25 g/cm3 in graphite, and3.53g/cm3 in daimond. Daimond is also made from carbon.

These are SOME properties of carbon.

Answer 3

carbon is and element. its also radioactive and used in the dating of archaeological finds. radioactive carbon decays uniformly. carbon is the base of our civilisation, our bodies contain calcium carbonate, (bones) carbon is organic. hydrocarbons form crude oil. carbon can be soft like charcoal, or pencil leads, carbon can be, graphite, or diamond. graphite is incredibly conductive to electrical current. noli, illegitium carborundum...which is roman, for "dont let the bastards grind you down"

Answer 4

Physical - properties of non metals, dull, brittle
