WebThe Atoms Class 12 notes is a deep dive into the matter. Students have been studying about atoms since junior classes; however, this is the most detailed version yet. Class 12 requires a deeper understanding of topics which is what this chapter offers. It helps them to understand the atomic spectra in detail. WebBohr’s atomic model:-. (a) The central part of the atom called nucleus, contains whole of positive charge and almost whole of the mass of atom. Electrons revolve round the nucleus in fixed circular orbits. (b) Electrons are capable of revolving only in certain fixed orbits, called stationary orbits or permitted orbits.

WebFeb 2, 2024 · Rutherford’s observations and results: – Most of the a -particles pass through the gold foil without any deflection. This shows that most of the space in an atom is empty. – Few a-particles got scattered, deflecting at various angles from 0 to θ. This shows that atom has a small positively charged core called ‘nucleus’ at centre of ... WebThe disparity in the quantum of machine production in India and that in other countries leads to.
