The dot-and-cross diagram for molecular oxygen in the ground state. The oxygen nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins. The above three-dimensional LDQ structures are useful for visualising the molecular structures, but they can be laborious to construct.
Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
Full structural formula of the methane molecule, the simplest alkane, and the principal component of natural gas, showing the bond lengths and angles. Date: 23 December 2010: Source: Own work based on: File:Methane-CRC-MW-dimensions-2D.png: Author
Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.
Complete revamp, giving a better likeness to File:Methane-CRC-MW-3D-vdW.png. Gradients are vastly improved, as are the sizes and shapes of atoms. Uploading this way (rather than as a separate image) would save numerous edits to target articles. 17:03, 24 October 2006: 1,100 × 1,100 (5 KB) Dbc334
Some inorganic solids dissociate - or crack - into molecular species heating or upon dissolving, e.g. Aluminium chloride. In such cases it is helpful to depict both the molecular and the nonmolecular forms. Some important chemical species cannot be easily represented with simple pictures, e.g. hydrochloric acid and non-stoichiometric compounds.
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]
