Alkaline earth metal The alkaline earth metals are six chemical elements in column (group) 2 of the Periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).[1] The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.[2]

Berkelium Berkelium is a transuranic radioactive chemical element with symbol Bk and atomic number 97.It is a member of the actinide and transuranium element series. It is named after the city of Berkeley, California, the location of the University of California Radiation Laboratory where it was discovered in December 1949.n Earth, berkelium is mostly concentrated in certain areas, which were used for the atmospheric nuclear weapons tests between 1945 and 1980, as well as at the sites of nuclear incidents, such as the Chernobyl disaster, Three Mile Island accident and 1968 Thule Air Base B-52 crash.

Beryllium chloride Beryllium chloride is an inorganic compound with the formula BeCl 2. It is a colourless, hygroscopic solid that dissolves well in many polar solvents. Its properties are similar to those of aluminium chloride, due to beryllium's diagonal relationship with aluminium.eryllium chloride is an inorganic compound with the formula BeCl 2.

How many protons, neutrons, and electrons does beryllium have? Beryllium (Be) has an atomic number of 4. This means it is the fourth lightest element, and 4th in the periodic table. More importantly, this means it has 4 protons in the nucleus. Now, its atomic weight is 9. The weight of any atom is, roughly speaking, the sum of the number of protons and neutrons in the nucleus.

Beryllium: the essentials Beryllium is a Group 2 (IIA) element. It is a metal and has a high melting point. At ordinary temperatures, beryllium resists oxidation in air. Beryllium compounds are very toxic.Its ability to scratch glass is probably due to the formation of a thin layer of the oxide.n fact, compounds containing beryllium are poisonous. Beryllium is found in a number of minerals. The most important minerals are beryl, [Be 3 Al 2 (SiO 3) 6 ], which is often found as hexagonal prisms, and bertrandite [4BeO.2SiO 2 .H 2 O].
