![]() When atoms are formed from protons, neutrons, and electron, some mass is converted into energy, called the binding energy. We cannot use these data to calculate the mass of a given atom, because the mass of a nuclide is not simply the sum of the masses of its fundamental particles. In atomic mass units the fundamental particles have the following masses Thus, atom consists of a heavy positively charged nucleus in the centre containing all protons and the electrons were revolving around the nucleus so that the centrifugal force balances the force of attraction.Ītomic number and mass number: The general notation that is used to represent the mass number and atomic number of a given atoms is $_\] It was therefore, concluded that there was sufficient empty space within the atom and small heavy positively charged body at the center called nucleus. Most of the particles passed through the foil undeflected, a few were deflected through small angle while very few were deflected back. Rutherford’s model of atom: A thin foil of gold was bombarded with -particles. Rutherford’s -rays scattering experiments. ![]() Structure of Atom Chapter at a Glance - Class 11 NCERT.
