Question

what are the limitations of rutherford's model of the atom ​

Answer 1

Answer

The major limitation of rutherford's model of the atom is that it does not explain the stability of the atom .

This will be clear by below discussion ;

In Rutherford's model of the atom the negatively charged electron revolving around the positively charged in nucleus in the circular path . change the direction of motion of electron is moving in a circular path changes continuously there for the motion of electron moving around the nucleus is accelerated . Now according to the "electromagnetic theory of physic " the charge electron undergoing accelerated motion around the nucleus will lose their energy continuously by radiation . the speed of electron will therefore go on decreasing they will be attracted more strongly by the oppositely charged nucleus they will come more and more close to the nucleus and ultimately fall into the nucleus by taking a spiral path . this should make the atom very unstable due to which the atom should collapse quickly . This , however does not happen . the electron do not fall into the nucleus atom and are very stable and do not collapse on their own . The rutherford's model however does not explain the stability of an atom.

Answer 2

Answer:

According to Rutherford's model of an atom, electrons revolve around the nucleus in fixed orbits. But, an electron revolving in circular orbits will not be stable because, during the revolution, it will experience acceleration. Due to acceleration, the electrons will lose energy in the form of radiation and fall into the nucleus. Hence, the atom would be highly unstable and would eventually collapse.
