Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Beryllium. The chemical symbol for Phosphorus is P. As an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free element on Earth.

A possible crystal structure of Beryllium is hexagonal close-packed structure. Describe the structure of the beryllium atom. The chemical symbol for Gold is Au. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. The chemical symbol for Lawrencium is Lr. 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. Elemental sulfur is a bright yellow crystalline solid at room temperature. You should include the number of each type of particle and where it is found in the atom. Beryllium is a chemical element with symbol Be and atomic number 4. In fact their absorption cross-sections are the highest among all stable isotopes.
