How does a pencil write on paper because there both wood?

The number 2 is typically used in the United States to indicate medium softness, while in other countries, the same pencil may be labeled as HB.

The pencil works via a soft graphite core being wrapped in a durable wooden sheath. This allows the graphite to be exposed as needed to write.

Is pencil lead metalic or nonmetalic?
It is non metallic. The pencil 'lead' is graphite which is a common mineral, a soft carbon
What is a black mineral that's waxy and soft and can coat gold nuggets?
The mineral that fits that description is graphite. It is soft, and has an oily or greasy feel. When it was first found in Britain, it was used to mark sheep! Today we use processed and prepared graphite as pencil lead. A link can be found below.
