a chemical element, atomic number 99, atomic weight 254. (See Appendix 6.)

ein·stein·i·um (Es),

(īn-stīn'ē-ŭm),
An artificially prepared transuranium element, atomic no. 99, atomic wt. 252.0; it has many isotopes, all of which are radioactive (252Es has the longest known half-life, 1.29 years).

einsteinium (Es)

[īnstī′nē·əm]
Etymology: Albert Einstein, German-born physicist and Nobel laureate, 1879-1955
a synthetic transuranic metallic element. Its atomic number is 99. The mass of its longest-lived, best-known isotope is 254. Einsteinium was first found in the debris from a hydrogen bomb explosion. It decays rapidly into berkelium.
