具有高密度的金属通常被称为反应金属，它们传导电流和吸收热量的能力是无可比拟的。它们在自然界中很少以固态形式出现，常常是同一些其他的特殊物质在原子层面结合在一起。

Very dense metals are often called reactive metals, as their ability to conduct electrical currents and absorb heat is unparalleled. Rarely found in a natural solid state, they are instead usually assembled on an atomic level from particulate matter found in other forms.
