NCERT Solutions For Class 12 Physics Chapter 13 Nuclei 13.2 Size Of The Nucleus

Overview of topic:

Before Rutherford’s experiment, the best model of the atom that was known to us was the Thomson or “plum pudding” model. In this model, the iota was accepted to comprise a positive material “pudding” with negative “plums” appropriated all through. Afterward, Rutherford’s alpha-molecule dispersing test changed the manner in which we think about nuclear construction. Rutherford coordinated light emissions particles at meager gold foil to test this model and noticed how the alpha particles dissipated from the foil.

    In the trial, Rutherford showed us that the iota was for the most part a vacant space with the core at the middle and electrons rotating around it. At the point when alpha particles were terminated towards the gold foil, Rutherford saw that 1 out of 20000 particles went through a shift in course of movement of in excess of 90 degrees. The rest 19999 particles digressed from their direction by a tiny edge. This prompted an end that the iota consisted of an unfilled space with the vast majority of the mass amassed at the middle in little volumes. This volume in the middle was named as ‘the core’; Latin for ‘little nut’.

    The order of size of the nucleus is Fermi (10^-15 m). The request for a distance of the first electron from the core is Angstrom (10^-10 m) and the radius of a golf ball is of the order of cm (10^-2 m).
