   the chemical symbol for einsteinium, a transuranic element
   with atomic number 99. the atomic weight of the longest-lived
   isotope, with a half-life of 276 days, is 254. the first
   isotope discovered, having atomic weight 253 and a half-life
   of 20 days, was recognized in 1952 in the debris from a
   hydrogen bomb test. as much as 3 micrograms of einsteinium
   were produced by a complex process involving long irradiation
   of plutonium isotopes in nuclear reactors. its chemical
   properties are those of a trivalent actinide element. --hcp61
