Rubidium (Rb) is an alkali metal.
Germanium is classified as a metallic element (some sources list it as semi-metallic)
A metalloid is an element that has both metallic and nonmetallic properties. When combined they form an alloy. Metalloids are usually semiconductors.
The items that contain more than one element and have metallic properties are known as alloys. They can be an intermetallic compound that lacks phase boundaries, a metallic phase mixture, or a solid element solution.
Metallic
It is metal as it conducts electricity and it is on the left side of that big black line in the periodic table. It is in fact used in wires for it's conductive properties.
no it is metallic
Assuming that "least nonmetallic" means the same as "most metallic", francium.
Antimony is a metalloid which means that it has metallic and nonmetallic properties and it is element 51 in the Periodic Table lying in the diagonal metalloids in the p group. The metallic and nonmetallic properties may be, for example, that it is grey and shiny like a metal but it may also be brittle and not conduct heat and electricity like a nonmetal.
Rubidium. Metallic character increases as you move down and to the left on the periodic table.

Rubidium (Rb) occurs naturally in minerals such as Pollucite, Carnallite and Lepidolite.
