[26] Because it does not blend geochemically with those elements that constitute the majority of the crustal mass, mercury ores can be extraordinarily concentrated considering the element's abundance in ordinary rock. Records are incomplete and unclear, but government commissions have estimated that some two million pounds of mercury are unaccounted for. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype.

It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities. The chemical symbol for Beryllium is Be. Mercury is a chemical element and the only common metal which is liquid at ordinary temperatures. The size and mass of atoms are so small that the use of normal measuring units, while possible, is often inconvenient. Organomercury compounds are always divalent and usually two-coordinate and linear geometry. One example is Hg2+3(AsF−6)2.[41]. Mercury(II) fulminate is a primary explosive which is mainly used as a primer of a cartridge in firearms. Its properties are thus intermediate between those of chlorine and iodine.
