cadmium
Cadmium.
The lowest atomic weight between iron and tin is that of silver.
Cadmium is the least metallic among zinc, iron, silver, and cadmium. Cadmium has a lower metallic character compared to the other elements listed.
An alloy contains at least one metallic element. Alloying involves mixing a metal with one or more other elements to enhance its properties, such as strength or corrosion resistance.
The element following the 3rd periodic table element (lithium) is beryllium, which exhibits metallic character. Beryllium is a metal with properties such as high melting and boiling points, luster, and electrical conductivity.
Assuming that "least nonmetallic" means the same as "most metallic", francium.
Potassium and sodium are considered to be the least ductile metals. Gold and platinum on the other hand are the most ductile metals.
Refined and polished, it is indistinguishable from silver, at least upon casual inspection.
When gold bonds with itself, it forms a metallic bond. Metallic bonding is characterized by the sharing of electrons among many atoms in a metal structure, leading to properties like high electrical conductivity, malleability, and ductility.
Ionic compounds do not require the presence of a metal, for example ammonium chloride is ionic and does not contain a metallic element. What is true is that the majority of ionic compounds involve at least one metal.
Silver is not highly reactive and is considered a noble metal. It does not easily react with most chemicals but can react with sulfur compounds in the air, leading to tarnishing or discoloration of the metal.
Francium is the least electronegative element
