Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic.It seldom occurs in its elemental state or as pure ore compounds in the Earth's crust. It is an alkali metal, the most reactive group in the periodic table, having properties and similarities with both other alkali metals and other period 5 elements.For example, rubidium has 5 electron shells, a property found in all other period 5 elements, whereas its electron configuration's ending is similar to all other alkali metals: s 1. Look, first of all you should know some properties of metal, nonmetal and semimetal (metalloid).

Sulfur Other Nonmetal. Despite the lack of specificity, the term remains in use in the literature of chemistry.. Period 1, which only contains two elements (hydrogen and helium), is too small to draw any conclusive trends from it, especially because the two elements behave nothing like other s-block elements. Chalcogen This includes the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides.On the periodic table, metals are separated from nonmetals by a zig-zag line stepping through carbon, phosphorus, selenium, iodine, and radon.These elements and those to the right of them are nonmetals. Helium (He) Nonmetal Noble Gas. Some sources refer to polonium as a metalloid, although it has some metallic properties. A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals.There is no standard definition of a metalloid and no complete agreement on which elements are metalloids.
