· BERYLLIUM, or Glucinum (symbol Be, atomic weight ), one of the metallic chemical elements, included in the same subgroup of the periodic classification as magnesium. It was prepared in the form of its oxide in 1798 by L. N. Vauquelin (Ann. de chimie, 1798, xxvi. p. 155) from the mineral beryl, and though somewhat rare, is found in many minerals.

The next three elements (lithium, beryllium and boron) were formed mostly by cosmic ray spallation, and are thus rarer than heavier elements. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The mineral or gemstone chrysoberyl is an aluminate of beryllium with the formula BeAl 2 O 4.
