Symbol · Actinium · Electronegativity. The elements can be placed in the periodic table. The position of an element provides information about its properties. Most elements are metals, with different.
The current structure of the periodic table was drawn up in after the Nobel-prize winning chemist Glenn Seaborg suggested the actinides - rare radioactive elements - belonged in a separate part of the table which is known as 'f-block'. The most important minerals are beryl, [Be 3 Al 2 SiO 3 6 ], which is often found as hexagonal prisms, and bertrandite [4BeO.
