Feb. 18, 2025 — It may be the smallest, shortest chorus dance ever recorded. An international team of researchers observed how electrons, excited by ultrafast light ...

This video explains covalent bonding. A covalent bond is a shared pair of electrons. Covalent bonding forms molecules. Substances with small molecules have low melting and boiling points and do ...

Use the diagram on page 130 Teaching Secondary Chemistry which summarised how different macroscopic structures relfect different ways of bonding atomic cores together with valence electrons.

Teaching that is consistent with the idea of a spectrum of bonding will help students when they go on to further study. It may not be asvisable to introduce it as a way of thinking before students ...
