Temporary name of the chemical element with atomic number 105. It was first synthesized and identified by A. Giorso, M. J. Nurmia, J. A. Harries, K. A. Y. Eskola and P. Escola at Lawrence Radiation Laboratory in Berkeley, California. They proposed the name hahnium (symbol, Ha), honoring the German physicist Otto Hahn. A conflicting claim from Dubna urged the name nielsbohrium. In August 1994 a panel of the International Union of Pure and Applied Chemistry (IUPAC) recommended it be called joliotium, for the French physicist Frederic Joliot-Curie.
In 1997, the IUPAC Commission on Nomenclature of Inorganic Chemistry recommended the name dubnium (symbol, Db), in honor of Dubna, commenting
Unnilpentium or Hahnium.
Ununpentium has 115 protons in the nucleus.
Unnilpentium is now officially named as Dubnium (Db) after the Russian town of Dubna. It is not found in nature and is synthesized in the laboratory.
who is considered to be the father of history
yesterday!! :)
The melting point of unnilpentium is not known today.
A strange and long history of the name: nielsbohrium, hahnium, unnilpentium, joliotium and finally, after 1997 - dubnium (the official name of IUPAC).
Unnilpentium or Hahnium.
Ununpentium has 115 protons in the nucleus.
Unnilquadium Unnilpentium Unnilhexium Unnilseptium Unniloctium Unnilennium Ununnilium Unununium Ununbium
Unnilpentium is now officially named as Dubnium (Db) after the Russian town of Dubna. It is not found in nature and is synthesized in the laboratory.
Dubnium (Db), a transition metal, also known by the following names: Unnilpentium (Unp), Joliotium (Jl), Hahnium (Ha).
Unnilpentium - UNP Element 105 is Dubnium (Db). It was first artificially created by Albert Ghlorso and co-workers in the city of Dubna, Russia, in 1970. This element had previously been called Hahnium, after German chemist Otto Hahn.
