Product Information

Mendelevium, which is a synthetic chemical element with the symbol Md (formerly Mv) and the atomic number 101, was named after Mendeleev. It is a metallic radioactive transuranic element in the actinide series, usually synthesized by bombarding einsteinium with alpha particles. The Collector's Edition Display contains ampules of the gaseous elements (Xenon, Krypton, Argon, Neon, Helium, Oxygen, Nitrogen, and Hydrogen).

His last words were to his physician: "Doctor, you have science, I have faith," which is possibly a Jules Verne quote.

What had begun to seem like a threat or trouble for the periodic table turned out to be a short lived concern. The classification of the higher atomic number elements is still very much governed by the periodic table regardless of the presence of relativistic effects. Döbereiner and triadsA special place among oxide glasses is occupied by fused silica or silica glass (SiO 2). It is the most refractory glass, it has a wide transparency window in the optical region and an abnormally low coefficient of thermal expansion (CTE) equal to 5.5·10 −7/K −1(LeLosq et al., 2019). These determine its wide range of applications—from UV lamps to optical elements. It is thanks to the development of silica glass technology and the production of optical fibers that the worldwide implementation of broadband Internet access has become possible (Ballato and Dragic, 2016). The elements in group 1, for example, all have one outer-shell electron although they differ in their inner shell structures. An integrated supply risk index from 1 (very low risk) to 10 (very high risk). This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores.
