Rutherford Gold Foil Experiment | | Class 09 | | Structure of Atom | |

Rutherford Gold Foil Experiment || Class 09 || structure of Atoms|| Observation of Rutherford atomic model was 1. Most of the fast moving Alpha particle passes through the gold foil 2. Some of Alpha particle get deflected by Gold foil in a small angles 3.Very surprisingly one out of every 12000 particles appeared to rebound. conclusion of Alpha particle scattering experiment 1. most of the space inside the atom is empty this is because most of the Alpha particle passes through the gold foil without getting deflected 2. all the positive charge of the atom occupy in a very little space inside the atom this is because very few particles were deflected from their path during Alpha particle experiment 3. all the masses and positive charge of the atom with concentrated in a very small volume within the atom called nucleus this is because a very small fraction of Alpha particles are deflected buy 180 degree Rutherford Model of an atom 1. there is a positively charged centre in an atom Colony place where all the mass of an atom resides 2. electron revolve around the nucleus in a well definite orbit 3. the size of the the necklace is very small as compared to the size of the atom Drawback of Rutherford Model of atom Rutherford experiment fail to describe from where electron get energy during revolution in a fix Orbit. this is because during the revolution in a circular path electron radiate energy and finally fall into the nucleus and therefore declared as of an atom is highly unstable.
