Metals

What property of metals allows them to be drawn into wires?

What temperature is generally regarded as the point at which a substance can conduct electricity to be classified as a metal in physics?

What type of bond between atoms or molecules in a metal gives rise to its properties like ductility and malleability?

Under what conditions can some materials classified as nonmetals become metallic?

Which nonmetal gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure?

Properties of Metals

Metals can be drawn into wires due to ductility, which is a result of their ability to deform under tensile stress without breaking.
Metallic bonding allows layers of atoms to slide over one another, contributing to this property.

Conductivity in Metals

A substance is typically considered to be a metal when it conducts electricity at temperatures above its melting point, which varies for different metals.

Bonding in Metals

The properties of ductility and malleability in metals stem from metallic bonds. These bonds involve a 'sea of electrons' that allows atoms to move relative to one another without fracturing.

Transition of Nonmetals

Certain nonmetals can exhibit metallic properties under extreme conditions, such as high pressure or specific temperature thresholds, allowing them to conduct electricity.

Nonmetal to Metal Transition

Carbon, specifically in the form of graphite, transitions to a metallic state when subjected to pressures between 40,000 and 170,000 times atmospheric pressure, enhancing its conductivity.
