realised a key component was missing from the nitrogen cycle equations. The biochemical equations would not balance unless he explicitly accounted for the transfer of electrons between compounds ...

Researchers at the University of Oklahoma have developed a breakthrough method of adding a single nitrogen atom to molecules, unlocking new possibilities in drug research and development.

If it has 7 protons, that’s nitrogen. But the logic of the periodic table also relies upon the number and organisation of electrons in an atom. Let’s take chlorine as an example. It is ...
