carbon
we all Know caRBON IS EARTH'S LIFE
WITHOUT CARBON WE DON'T LIVE ,WE DON'T MAke.....
Basicly carbon 3 form in nature. 1. diamon ,2.graphite,3.fulrine
Diamond a option of pure form carbon in the earth,that contain maximam persantage of carbon.Diamond also contain non electric properties.In diamond carbon molecule packed in titely position,any blank space are not present in diamond. NOT ONLY no moment of carbon molecule BUT ALSO no free electron are present. So that reason Diamond not A CONDUCTER of light.
YAHHHH....
PENCIL are make by graphite and wood.
graphite make by many layer of atomic molecule that are slipy in nature to just another layer. that properties make graphite silky and siny.We also use macine to low the fraction...
graphite molecule are not closely packed so it stracture so electron movement are posible. THAT REASON-GRAPHITE are conducter of light...
anoter use of graphite- IN nuclear rxn controler...
