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 .
Beryllium occurs in the Earth's crust at a concentration of two to six parts per million (ppm), [56] much of which is in soils, where it has a concentration of six ppm. Beryllium is one of the rarest elements in seawater, even rarer than elements such as scandium, with a concentration of 0.2 parts per trillion.

As atomic number increases, shells fill with electrons in approximately the order shown in the ordering rule diagram. The filling of each shell corresponds to a row in the table. In the f-block and p-block of the periodic table, elements within the same period generally do not exhibit trends and similarities in properties (vertical trends down ...

This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
Beryllium is the single exception to both rules, due to its low atomic number. [ 89 ] All of the alkali metals except lithium and caesium have at least one naturally occurring radioisotope : sodium-22 and sodium-24 are trace radioisotopes produced cosmogenically , [ 90 ] potassium-40 and rubidium-87 have very long half-lives and thus occur ...
