Chemical bonding force. Help me understand how chemists describe this force! So one proton has a positive charge. One electron has a negative charge. When we bring them together, that makes one hydrogen atom. The positive proton and the negative electron cancel each other out. Perfect! But that single hydrogen atom is NOT happy on its own even though the proton and the electron cancel each other out. Questions; Why does that hydrogen want to stick to another hydrogen to form H2? Why would that hydrogen want to stick to a neutron to form Deuterium when a neutron is electrically neutral? What name do chemists use to describe the force that attracts 2 hydrogen atoms together? Any help would be appreciated. Sometimes its the simplest things that catch me out. John.
