Chemical bonding occur during chemical reaction because of the principle of octet rule.
Octet Rule:
During chemical reaction, atom may gain, loss, or shared the minimum number of valence electron in order to have the same electron configuration of the nearest noble gas.
When atom gain or loss electron, atoms will be having positive or negative charges. Positive charged atoms will be attracted by negative charged atom creating an ionic bond.
Covalent bond are formed between nonmetal elements which shares electrons to have the same electron configuration of the nearest noble gas.
There is only one stable atom that does not have neutrons. It is an isotope of the element Hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom.
A summary is not a rewrite of the original piece and does not have to be long nor should it be long.
