According to Maxwell theory of electromagnetic radiation, a charged body moving under the influence of attractive forces loses energy continuously in the form of electromagnetic radiation. Thus, the electron is a charged body and it should emit radiations while revolving around the nucleus. As a result of this, the electron should lose energy at every turn and move closer and closer to the nucleus following a spiral path. Consequently, the orbit will become smaller and smaller and finally the electron would fall into the nucleus. In other words, the atom should collapse.
