can..  A metal is a chemical element that is a good conductor of
both electricity and [heat and forms cations and ionic bonds
with non-metals. In chemistry, a metal (Ancient Greek métallon,
μέταλλον) is an element, compound, or alloy characterized by
high electrical conductivity. In a metal, atoms readily lose
electrons to form positive ions (cations). Those ions are
surrounded by delocalized electrons, which are responsible for
the conductivity. The solid thus produced is held by
electrostatic interactions between the ions and the electron
cloud, which are called metallic bonds.[1]   Metals are
sometimes described as an arrangement of positive ions
surrounded by a cloud of delocalized electrons. They are one of
the three groups of elements as distinguished by their
ionization and bonding properties, along with the metalloi
