Replacing a carbon atom in an aromatic ring with a nitrogen atom is one of those exercises that’s easy to do on paper with a pencil and eraser but tough to accomplish in a reaction flask.

Students will also be able to explain that the attraction between positive protons and negative electrons holds an atom together. Supplement in-class learning with interactive, multimedia-rich Google ...

Swapping an oxygen atom for a nitrogen atom, for example, is usually exceedingly difficult, much to the frustration of medicinal chemists. But now, thanks to researchers based at the Korea ...

All the elements in the Periodic Table are made from different atoms, and the structure of these atoms results in a gamut of phenomena from radioactive decay to nuclear power. When you purchase ...

The ability to alter complex molecules by a single atom at a time would be incredibly useful for medicinal chemistry—it would enable researchers to, for example, test the influence of different ...

Save guides, add subjects and pick up where you left off with your BBC account. We know that matter is made up of particles called atoms and that an element is a substance that is made up of only ...
