 channel for physics please subscribe my channel hello and welcome back to another episode of physics partner today we are going to discuss about the rutherford atomic model it was a major challenge before the scientists at the end of the 19th century to reveal the structure of the atom as well as to explain its important properties for this different atomic models were proposed after thompson's model failed to explain certain experimental results rutherford a british scientist conducted an experiment and based on the observation of this experiment gave rutherford atomic model rutherford atomic model is also called a nuclear model of atom rutherford perform an experiment known as gold foil experiment you can watch my detailed video about rutherford gold foil experiment on the same channel don't worry i will share the link in the description as well for his experiment and thin sheet of gold was bombarded with alpha particles he then studied the trajectory of these particles after their interaction with the gold foil based on the observations and conclusion of this experiment rutherford proposed an atomic structure of element let's see the features of rutherford atomic model number one most of the mass of an atom and the power to be charged particles were concentrated in an extremely small volume this region of the atom was called as a nucleus hit number two his model proposed that the negatively charged electrons surround the nucleus revolve around it with very high speed in circular paths these circular paths were named as orbits by him number three nucleus being a densely concentrated mass of horribly charged particles an electron being negatively charged particles are held together by a strong electrostatic force of attraction let's talk about the limitation of rutherford atomic model rutherford atomic model also failed to explain certain things like thompson's model although it was based on experimental observations rutherford model was not in accordance with maxville theory of electromagnetic radiation and it could not explain the stability of an atom he proposed the electrons to be revolving around the nucleus in fixed path called orbits as per maxville's theory electromagnetic radiation are emitted by accelerated charged particles and hence an electron which revolves around the nucleus should emit electromagnetic radiation this radiation from the electron would carry energy from the motion of the electron which would come at the cost of shrinking of orbits ultimately the electron would collapse in the nucleus if this were true the atom should be highly unstable and hence matter would not exist in the form that we know but we know the atom are quite stable another defect in rutherford model is that rutherford model did not say anything about the arrangement of electrons in an atom which made his theory incomplete although the early atomic model like thompson's model and rutherford model were inaccurate and failed to explain certain experimental results but they were the base for future developments in the world of quantum mechanics i hope this video is useful for you thank you very much for your listening take care of yourself and see you in the next video goodbye
