Rubidium is a chemical element with atomic number 37 which means there are 37 protons and 37 electrons in the atomic structure. It is one of the least reactive chemical elements and is solid under standard conditions. Au moins 27 radioisotopes ont été synthétisés. Because of its high chemical reactivity, barium is never found in nature as a free element. … The chemical symbol for Yttrium is Y. Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”. It is the electrons that are responsible for the chemical bavavior of atoms, and which identify the various chemical elements. Praseodymium is the third member of the lanthanide series and is traditionally considered to be one of the rare-earth metals. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars. Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. For uranium atom, the Van der Waals radius is about 186 pm = 1.86 ×10−10m. The chemical symbol for Germanium is Ge. The chemical symbol for Thallium is Tl. Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Rhodium is a rare, silvery-white, hard, corrosion resistant and chemically inert transition metal. Bromine is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3. The chemical symbol for Americium is Am. Picture of the RED30 detector that the researchers used for the dark matter searches.
