Periodic Table of the Elements - Non-Metals
Hydrogen can become metallic when exposed to extremely high pressures. Some allotropes of elements show more pronounced metal, metalloid or non-metal behaviour than others. The element carbon; its diamond allotrope is non-metallic, however the graphite allotrope is electrically conductive showing characteristic more like a metalloid.
