These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). Convert grams Copper to moles or moles Copper to grams ›› Percent composition by element. In the periodic table, potassium is one of the alkali metals. Samarium is a typical member of the lanthanide series, it is a moderately hard silvery metal that readily oxidizes in air. Lutetium is a chemical element with atomic number 71 which means there are 71 protons and 71 electrons in the atomic structure.
