Carbon (graphite) will conduct electricitySilicon metallic will conduct electricity
Graphite
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Generally, non metals are non conductors (with exceptions such as graphite, fullerene etc)
Water Graphite is an excellent electrical conductor.
Graphite is a form of carbon.
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.
Graphite is the only non-metal exception that can conduct electricity. Hence, even though graphite is a non-metal, it is used in batteries.
No.

Graphite is not metallic it just "shines" when the light shines on it
Graphite is a very soft material, and is non-toxic. It is easily machined.

A wetting fluid is capable of maintaining surface contact with a solid and its contact angles are less than 90 degrees (the angle starts from the wetted surface to the surface of the fluid). However non-wetting fluids are not willing to keep the contact area as large as wetting fluids and their contact angles are higher than 90 degrees. Imagine a droplet of mercury. As a non-wetting fluid, mercury remains still on a solid surface like a ball. It does not spread on the solid surface like water.
Carbon, when it is in the form of graphite.
