The nucleus of each nitrogen atom contains seven protons and seven neutrons. That is, it does until a collision happens. The incoming neutron hitting the nucleus causes a proton to shoot out of ...

The formula is H 2 O so the dot and cross diagram includes two H atoms and one O atom. H has 1 outer electron. O has 6 outer electrons. The H circles must each overlap the O circle. Nitrogen ...

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 ...

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 ...
