Graphite. Graphite is another allotrope of carbon; unlike diamond, it is an electrical conductor and a semi-metal. Graphite is the most stable form of carbon under standard conditions and is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. ...
Explain why diamond is an electrical insulator and graphite is an electrical conductor. Give three reasons why carbon is preferred over hydrogen in the relative atomic mass of an atom. Explain why as you go across Period 3, the atomic radius decreases. ...
Explain why diamond is an electrical insulator and graphite is an electrical conductor. How aluminium chloride is used in industries? Are the polymer strands in Teflon TM tape arranged randomly or in parallel? Explain. How do enzymes work? Explain briefly. ...
Important features of an electrical conductor include the following: It ensures free movement of electrons or ions through it. It has a zero electric field inside, which permits the movement of electrons or ions. Outside the conductor, the electric field is perpendicular to the conductor's surfac...
