[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.
The structure of phase 5 is believed to be similar, with generic formula [(Mg 3 (OH) 5 (H 2 O) x) n] n+ (Cl −) n (H 2 O) n(4−x). [ 17 ] The anhydrous forms of phase 3 and phase 5 have the same structure as Mg(OH) 2 : namely, layers of magnesium cations, each sandwiched between two layers of hydroxy or chloride anions.
Under the framework of valence bond theory, resonance is an extension of the idea that the bonding in a chemical species can be described by a Lewis structure. For many chemical species, a single Lewis structure, consisting of atoms obeying the octet rule, possibly bearing formal charges, and connected by bonds of positive integer order, is sufficient for describing the chemical bonding and ...
