The most stable known isotope, meitnerium-278, has a half-life of 4.5 seconds, although the unconfirmed meitnerium-282 may have a longer half-life of 67 seconds. The element was first synthesized in August 1982 by the GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany, and it was named after Lise Meitner in 1997.
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. 15 elements were named to honor 16 scientists (as curium honours both Marie and Pierre Curie). Four others have indirect connection to the names of non-scientists. [1]
Vanadium (named after Vanadís, another name for Freyja, the Scandinavian goddess of fertility) was originally discovered by Andrés Manuel del Río (a Spanish-born Mexican mineralogist) in Mexico City in 1801. He discovered the element after being sent a sample of "brown lead" ore (plomo pardo de Zimapán, now named vanadinite).
After her death in 1968, Meitner received many naming honours. In 1997, element 109 was named meitnerium. She is the first and so far the only non-mythological woman thus exclusively honoured (since curium was named after both Marie and Pierre Curie).
In the periodic table of elements, two chemical elements are named after a female scientist: Curium (element 96), named after Marie and Pierre Curie; Meitnerium (element 109), named after Lise Meitner
meitnerium, Mt, named after Lise Meitner, an Austrian physicist who was one of the earliest scientists to study nuclear fission (1982). 110. darmstadtium, Ds, named after Darmstadt, Germany, the city in which this work was performed (1994).
Elements which are named after currently existing countries and cities are as: Polonium, named after Poland [15] Francium and gallium, both named after France [16] Nihonium, named after Japan; Germanium was named for Germany [17] Beryllium was named after the mineral beryl, whose name may have come from Belur, a city in Karnataka state of India ...
