Transuranic Elements and their Production Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays

It is by far the most abundant element in the universe and makes up above 90% of Universe by weight. Hydrogen as water (H2O) is absolutely essential to life and it is present in all organic compounds. Hydrogen is lightest gas. Hydrogen gas was used in lighter-than-air balloons for transport but is far too dangerous because

Practical Report Experiment 1 Abstract In this experiment we found that you can calculate the density of elements with close presotion with crude experiments Introduction The aim of this experiment was to see how close you could measure the density of atoms with crude experiments. The second part of the experiment dealt with Solubility of large ions and their Hydration enthalpy. Hydration enthalpy is the enthalpy change when 1 mole of an ionic substance dissolves in a solution to give a solution

Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic transition metal‚ it has historically been sometimes classified as a rare earth element‚ together with yttrium and the lanthanoids. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present in most of the deposits of rare earth and uranium compounds‚ but it is extracted from these ores in only a few mines worldwide. Because of the low availability
