The study of molecules by molecular physics and theoretical chemistry is largely based on quantum mechanics and is essential for the understanding of the chemical bond. The simplest of molecules is the hydrogen molecule-ion, H 2 + , and the simplest of all the chemical bonds is the one-electron bond.
people think that j.j. Thompson discovered the electron in 1897, but nikola tesla has records of his discovery of negatively charged particles being responsible for electric c â¦ urrents years before Thomson discovered it. Atoms are able to bond together because of what is known as the octet rule, which is followed by mâ¦. 2  Understanding Electrons An electron is a subatomic particle that revolves around the protons and neutrons in an atom's central nucleus.
