Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond , and exceeds that of most metals. [ 12 ]
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

Carbon monoxide exemplifies a Lewis structure with formal charges: To obtain the oxidation states, the formal charges are summed with the bond-order value taken positively at the carbon and negatively at the oxygen. Applied to molecular ions, this algorithm considers the actual location of the formal (ionic) charge, as drawn in the Lewis structure.
Nitric oxide is a heteronuclear molecule that exhibits mixing. The construction of its MO diagram is the same as for the homonuclear molecules. It has a bond order of 2.5 and is a paramagnetic molecule. The energy differences of the 2s orbitals are different enough that each produces its own non-bonding σ orbitals.
Beryllium bromide is the chemical compound with the formula BeBr 2. It is very hygroscopic and dissolves well in water . The Be 2+ cation, which is relevant to BeBr 2 , is characterized by the highest known charge density (Z/r = 6.45), making it one of the hardest cations and a very strong Lewis acid .
Lithium telluride (Li 2 Te) is an inorganic compound of lithium and tellurium. Along with LiTe 3, it is one of the two intermediate solid phases in the lithium-tellurium system. [3] It can be prepared by directly reacting lithium and tellurium in a beryllium oxide crucible at 950°C. [4]
Beryllium iodide is an inorganic compound with the chemical formula Be I 2. It is a hygroscopic white solid. The Be 2+ cation, which is relevant to salt-like BeI 2 , is characterized by the highest known charge density (Z/r = 6.45), making it one of the hardest cations and a very strong Lewis acid .
