Water molecule showing polarity

This is a colour graphic representation of a water molecule. It depicts the structural formula of water superimposed on a space-filling model and an electron-density isosurface. The diagram is colour-coded to show the dipole nature of the molecule.

Iodine molecule

This is a colour image of a model of a molecule of iodine, I₂. In this model, two iodine atoms are represented by deep red spheres held together by a grey rod that represents a covalent bond.

Image

Hydrogen molecule

This is a colour image of a model of a molecule of hydrogen, H₂. In this model, two hydrogen atoms are represented by grey-white spheres held together by a grey rod that represents a covalent bond.

Image

Water molecule

This is a colour image of a model of a molecule of water, H₂O. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The water molecule contains one oxygen atom (the red sphere) and two hydrogen atoms (the grey-white spheres).

Image

Ethanol molecule

This is a colour image of a model of a molecule of ethanol, CH₃CH₂OH. In this model, atoms are represented by coloured spheres held together by grey rods that represent covalent bonds. The molecule contains two carbon atoms (the black spheres), one oxygen atom (the red sphere) and six hydrogen atoms (the grey-white spheres).

Bromine monofluoride molecule

This is a colour image of a model of a molecule of bromine monofluoride, BrF. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The bromine monofluoride molecule contains one bromine atom (the brown sphere) and one fluorine atom (the blue-grey sphere).

Image

Oxygen molecule

This is a colour image of a model of a molecule of oxygen, O₂. In this model, two oxygen atoms are represented by red spheres held together by grey rods that represent a double covalent bond.
