Why do only atoms take part in chemical reactions?

As we know that , All the atom other than Noble gases have less than 8 electron in their outermost shells . In other words , the outermost shell of these atom do not have stable electronic configuration ( octate rule) . Therefore they combined with other atom or itself i. read more

Atom take parts in chemical reaction in order to gain it's stable electronic configuration i.e Noble gas electronic configuration. According to modern view the atom take part in chemical reaction to acquire a state of minimum energy . Because As we known every system in the universe has a natural tendency to attained a state of minimum energy. read more

Chemical reactions involved the transfer or sharing of electrons. A couple of hydrogen atoms, for example can react with a molecule of propene to form propane ( 2 H + nC3H6 ---> nC2H8) The key is the original elements are present in the product of the reactions. read more
