Why atoms bond together?
Why atoms bond together? All form of movement or interaction in the universe is for one goal only, reaching the stability. when atoms associate with each other (the resultant product is called molecule) it forms a more stable product(molecule) from the former separated atoms each on its own. When we said stable its actually meant lower in energy i.e the atoms will release energy (usually in form of heat) to form a molecule which by default will contain lesser energy. In contrast breaking bond needs to apply energy. In general bond formation release energy ,bond breakage absorb energy. Some groups in the periodic table contain elements that there atoms are stable, so they do not react at all, called NOBLE ELEMENTS those are group 8A in the periodic table and those elements contain eight electrons (octet) at there outer shell (valence shell) except Helium it contain only two electrons, it seems as if all other elements in the periodic table are trying to mimic those elements i...
