Molecule exercise II (Polarity)

An exercise about the polarity of molecules.

Molecule exercise VII (Organic nitrogen compounds)

An exercise about the groups and structure of organic nitrogen compounds.

Development of the atomic model

Major phases in the history of theories and views about the structure of the atom.

Covalent bonds in benzene molecules

In benzene there are sigma bonds and delocalised pi bonds between carbon atoms.

Electron configuration of calcium

This animation shows the electron configuration of the calcium atom.

Formation of hydrogen molecules

Hydrogen atoms within hydrogen molecules are held together by a covalent bond.

Hydrogen (H₂)

Colourless, odourless, lighter-than-air gas. The most common chemical element in the universe.

Nitrogen (N₂) (intermediate)

A colourless, odourless, non-reactive gas, it constitutes 78.1% of Earth´s atmosphere.

Structure of nitrogen molecules

This animation demonstrates the structure of nitrogen molecules, with one sigma and two pi bonds holding the atoms together.
