29. Rutherford's α particle scattering experiment eventually led to the conclusion thatA) neutrons are buried deep in the nuclcusB) the point of impact with matter can be precisely determinedC) electrons occupy space around the nucleusD) mass and energy are related |

Answer» Conclusion of Rutherford's scattering experiment: Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space. A very small fraction of α-particles were deflected by very large angles, indicating that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom. Rutherford's Nuclear Model Of Atom On the basis of his experiment,Rutherford put forward the model of an atom, which had the following features: There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus. The electrons revolve around the nucleus in well-defined orbits. The size of the nucleus is very small as compared to the size of the atom. option C is most accurate A, is also partially correct |
