[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.
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 ]
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 .
A diatomic molecular orbital diagram is used to understand the bonding of a diatomic molecule. MO diagrams can be used to deduce magnetic properties of a molecule and how they change with ionization. They also give insight to the bond order of the molecule, how many bonds are shared between the two atoms. [12]
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 .
Basic beryllium acetate has a tetrahedral Be 4 O 6+ core with acetates (CH 3 CO 2 −) spanning each of the pairs of Be 2+ centres. [3] [4] It consists of interlocking six-membered Be 2 O 3 C rings. The structure is relevant to its considerable stability (the compound is distillable at 330 °C). Schematic structure of basic beryllium acetate
Structure of beryllium fluoride (BeF 2), a compound with a linear geometry at the beryllium atom. The linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands ) placed at a bond angle of 180°.
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 .
