Why does graphite conduct electricity whereas - …

A material’s ability to conduct electricity is determined by the nuer and mobility of its free electrons. In diamond, each carbon atom uses all four of its valence electrons to bond with neighboring atoms. That doesn’t leave any electrons free f

A Basic Primer on Copper, the Red Metal

Strength: Copper is a weak metal with a tensile strength about half that of mild carbon steel. This explains why copper is easily formed by hand but is not a good choice for structural appliions. Toughness: Copper may not be strong, but it is not easy to break due to its high toughness. This property comes in handy for piping and tube appliions, where a rupture can be dangerous and

Metalloid - Wikipedia

2019-4-17 · A metalloid is an element that possesses properties of both metals and non metals, and which is therefore hard to classify as either a metal or a nonmetal. This is a generic definition that draws on metalloid attributes consistently cited in the literature. Difficulty of egorisation is a key attribute.

Why does graphite conduct electricity - Why Center

These electrons are what enables electricity to flow through the metal. Because the structure of the metal and its free valence electrons has a lot to do with how well it conducts electricity, some metals are better than it than others. While nearly all metals and graphite can conduct electricity, some have a better atomical structure for doing so.
