Some exciting #outreach on the horizon! Preparing for the #SundayFunday celebration of the International Year of the Periodic Table @iypt2019 at @berkeleyscience. Do you know all the elements discovered in @BerkeleyLab? Check the hashtag #ElementsOfBerkeleyLab.
It's been a great year full of new connections with STEM and academia Twitter community, creative time with the #ElementsOfBerkeleyLab and #StreetsOfBerkeleyLab series, and a great inspiration for #scicomm and #careerdevelopment. Thank you! #MyTwitterAnniversary
Thanks to #ElementsOfBerkeleyLab series, I've learned about mysterious Przybylski's star, showing in its spectrum short-living actinides, e.g. plutonium. What's the origin of its strange composition? A neutron star companion? Island of stability elements? https://t.co/iaP7N0K8Oi
Motivated by scientific curiosity, the discovery of technetium (Z=43) and its isotopes gave us the most commonly used radioactive tracer for imaging the brain, heart, thyroid, blood, kidneys, skeleton, and more. #BasicScienceMatters #IYPT2019 #16elements #ElementsOfBerkeleyLab
The empty space under iodine in the #PeriodicTable was filled in 1940 with astatine (Z=85). Instead of searching for its very rare natural sources as many tried, the @BerkeleyLab team created it with Bi and α-particles from a cyclotron #IYPT2019 #16elements #ElementsOfBerkeleyLab
Can you imagine a better person to honor with naming a chemical element after them than G. T. Seaborg, (co-)discoverer of 10 transuranic elements at @BerkeleyLab and #NobelPrize winner in chemistry? Seaborgium, Z=106.
#IYPT2019 #16elements #ElementsOfBerkeleyLab
70ies:
hahnium (@BerkeleyLab proposal)
nielsbohrium (@Joint_Institute proposal)
@IUPAC 1994: joliotium
@IUPAC 1997: dubnium
Poor element Z=105, 4 different names over 30 years. Finally named for Dubna, where it was co-discovered.
#IYPT2019 #16elements #ElementsOfBerkeleyLab
A. Ghiorso's team updating the #PeriodicTable with the new element co-discovered at @BerkeleyLab in 1961 with the Heavy Ion Linear Accelerator. Lawrencium (Z=103) is named for E. Lawrence, inventor of the cyclotron and founder of LBL. #IYPT2019 #16elements #ElementsOfBerkeleyLab
The controversy in choosing the name and claiming the discovery of the elements Z=102-106 is sometimes referred to as the Transfermium Wars. This is a good read about this complicated process: https://t.co/SRvLkBsNnu #IYPT2019 #16elements #ElementsOfBerkeleyLab
The discovery of the elements Z=102-106 was disputed for years between @BerkeleyLab and JINR, Dubna. Only in the 90s, @IUPAC credited the Russian team with the discovery of nobelium (Z=102) in 1966, named for the #NobelPrize founder. #IYPT2019 #16elements #ElementsOfBerkeleyLab
Named for D. Mendeleev, father of the #PeriodicTable, mendelevium (Z=101) was discovered by bombarding an Es target with a high-intensity α-particle beam from the @BerkeleyLab 60" cyclotron. Only 17 Md atoms were isolated in total! #16elements #ElementsOfBerkeleyLab #IYPT2019
Discovered by @BerkeleyLab in the fallout from the Ivy Mike nuclear test, fermium (Z=100) is named for the creator of the first nuclear reactor, Enrico Fermi. Although theoretically possible, a pure macroscopic sample of Fm has never been created. #IYPT2019 #ElementsOfBerkeleyLab
The element with the highest atomic nb (Z=99) observed in its pure form in macroscopic quantities is Einsteinium, named for you-know-who. Es was discovered in debris sent to @BerkeleyLab from the first successful hydrogen-bomb test. #IYPT2019 #16elements #ElementsOfBerkeleyLab
Californium (Z=98) is named after California, where it was first synthesized in 1950 at @BerkeleyLab. Cf-252, as a strong neutron emitter, is used, e.g., in neuron imaging (https://t.co/9BaPO3ZpSl), or in cervical cancer treatment #IYPT2019 #16elements #ElementsOfBerkeleyLab
Berkelium (Z=97) is named after the location of @BerkeleyLab, where it was discovered. Like most transuranic elements, it doesn't occur naturally on our planet. All Bk isotopes present when the Earth was formed are decayed by now. #IYPT2019 #16elements #ElementsOfBerkeleyLab
Curium (Z=96), first produced at @BerkeleyLab by bombarding Pu-239 with α-particles, is named for Marie Skłodowska-Curie and Piere Curie. It is used in spectrometers analyzing the chemical composition of samples on space missions. #IYPT2019 #16elements #ElementsOfBerkeleyLab
Americium (Z=95), discovered by the @BerkeleyLab team at the Met Lab of @UChicago, is named after America, because of its location below Europium (Z=63) in the #PeriodicTable. Am-241 is used in very small amounts in smoke detectors. #IYPT2019 #16elements #ElementsOfBerkeleyLab
Plutonium (Z=94) was discovered in 1940 by G. Seaborg's team using the 60-in cyclotron at @BerkeleyLab by bombarding U-238 with deuterons. Due to war secrecy (Pu was used in the "Fat Man" bombs) its discovery was announced only in 1948 #IYPT2019 #16elements #ElementsOfBerkeleyLab
The Radiation Lab (now @BerkeleyLab) led the discovery of 14 transuranic elements. The first one, #neptunium (Z=93) named after Neptune, as it follows uranium, is used to produce plutonium-238 used in spacecraft electrical generators.
#IYPT2019 #16elements #ElementsOfBerkeleyLab
To celebrate the International Year of the #PeriodicTable I would like to bring you for a fascinating journey through elements (co-)discovered in and by @BerkeleyLab from the transuranic elements to Technetium and Astatine. ⚛ #IYPT2019 #16elements #ElementsOfBerkeleyLab
