"hello everyone welcome to later this is priya and here we have a question about limitations of rutherford's model of the atom so i will tell you what are the limitations of rutherford model of atom so the first limitation is there is no expected stability there is no expected stability in the revolution of in the revolution of electron in an atom so he must fail to give the expected stability in the river revolution of electron in an atom around its orbit and the second one is charged particles radiate energy when they accelerated so charged particles radiate energy when accelerated thus changing revolving electrons so the electrons can jump from one orbit to the other orbit so hence these electrons to lose energy and would fall into the nucleus and the third is hence atoms must be highly unstable as we know atoms are highly unstable the matter would not exist in their known form which clearly is an assumption as atoms are highly stable as we know atoms are highly unstable and in the rutherfords model it has given that the matter would not exist in their known form which clearly isn't only the assumption as the atoms are stable so these are the limitations of rutherford's model of the atom hope you understand this video if you like my video please subscribe to our leader channel and if you have any doubts you can keep a message in comment box thank you"
