How many meta states does the first isotope to be synthesized in Am in 1944 have?
Isotopes of americium Americium (Am) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no known stable isotopes. The first isotope to be synthesized was Am in 1944. The artificial element decays into alpha particles. Americium has an atomic number of 95 (the number of protons in the nucleus of the americium atom).
1,1'-Azobis-1,2,3-triazole 1,1′-Azobis-1,2,3-triazole is a moderately explosive but comparatively stable chemical compound which contains a long continuous chain of nitrogen atoms, with an unbroken chain of eight nitrogen atoms cyclised into two 1,2,3-triazole rings. It is stable up to 194 °C. The compound exhibits cis–trans isomerism at the central azo group: the "trans" isomer is more stable and is yellow, while the "cis" isomer is less stable and is blue. The two rings are aromatic and form a conjugated system with the azo linkage. This chromophore allows the "trans" compound to be isomerised to the "cis" when treated with an appropriate wavelength of ultraviolet light.
