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 .
Even the compound beryllium fluoride, which is the most ionic beryllium compound, has a low melting point and a low electrical conductivity when melted. [ 12 ] [ 13 ] [ 14 ] All the alkaline earth metals have two electrons in their valence shell, so the energetically preferred state of achieving a filled electron shell is to lose two electrons ...
Beryllium azide, BeN 6 is known and beryllium phosphide, Be 3 P 2 has a similar structure to Be 3 N 2. A number of beryllium borides are known, such as Be 5 B, Be 4 B, Be 2 B, BeB 2, BeB 6 and BeB 12. Beryllium carbide, Be 2 C, is a refractory brick-red compound that reacts with water to give methane.

Many mixed ligand complexes are simply formed by addition of Lewis bases to diaryl and dialkylberyllium compounds. Many derivatives are known of the type BeR 2 L 2 and BAr 2 L 2 are known where L = thioether, pyridine, NHC, [14] and 1,4-Diazabutadienes. [15] Beryllium forms a variety of complexes with N-hetereocyclic carbenes (NHCs). [16] [17] [18]
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.
There are an almost infinite number of compounds that contain carbon due to carbon's ability to form long stable chains of C—C bonds. [ 16 ] [ 17 ] All organic compounds , those essential for life, contain at least one atom of carbon; [ 16 ] [ 17 ] combined with hydrogen, oxygen, nitrogen, sulfur, and phosphorus, carbon is the basis of every ...
The fourth shell contains one 4s orbital, three 4p orbitals, five 4d orbitals, and seven 4f orbitals, thus leading to a capacity of 2×1 + 2×3 + 2×5 + 2×7 = 32. [30] Higher shells contain more types of orbitals that continue the pattern, but such types of orbitals are not filled in the ground states of known elements. [45]
Small amounts of beryllium were synthesised during the Big Bang, although most of it decayed or reacted further to create larger nuclei, like carbon, nitrogen or oxygen. Beryllium is a component of 100 out of 4000 known minerals, such as bertrandite, Be 4 Si 2 O 7 (OH) 2, beryl, Al 2 Be 3 Si 6 O 18, chrysoberyl, Al 2 BeO 4, and phenakite, Be 2 ...
