WebDensity (g cm −3) Density is the mass of a substance that would fill 1 cm 3 at room temperature. Relative atomic mass The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average. Isotopes Web1 Mar 2007 · At 0.856 g/cc, elemental potassium is the second-least dense metal, after lithium. Generally, production processes extrude elemental potassium in imprecise cylindrical forms, further reducing density of the delivered product by inclusion of voids. Oxidation of potassium metal in storage Potassium is an aggressive reducing agent.
