Einsteinium is a synthetic chemical element; it has symbol Es and atomic number 99. It is named after Albert Einstein and is a member of the actinide series and the seventh transuranium element. Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.
Swedish surname eponym Named in honour of Glenn T. Seaborg, who discovered the chemistry of the transuranium elements, shared in the discovery and isolation of ten elements, and developed and proposed the actinide series. · Former names: eka-tungsten, [21] unnilhexium (Unh, '106'): temporary systematic name and symbol. [61] [22] Bohrium (Bh) 107
In 1994, a committee of IUPAC recommended that element 107 be named bohrium (Bh), also in honor of Niels Bohr but using his surname only. While this conforms to the names of other elements honoring individuals where only the surname is taken, it was opposed by many who were concerned that it could be confused with boron , which is called borium ...

This list of chemical elements named after people includes elements named for people both directly and indirectly. Of the 118 elements, 19 are connected with the names of 20 people.
Mendelevium was discovered by bombarding einsteinium with alpha particles in 1955, the method still used to produce it today. It is named after Dmitri Mendeleev, the father of the periodic table. Using available microgram quantities of einsteinium-253, over a million mendelevium atoms may be made each hour. The chemistry of mendelevium is ...
