Two important limitations of Rutherford nuclear model of the atom are as follows: (i) An electron revolving in a circular orbit is an example of accelerated motion. According to classical Physics, a particle in accelerated motion must radiate energy. Consequently, ...
Basic assumptions of Rutherford’s atom model are as follows: (i) The nucleus of an atom contains whole positive charge and almost whole mass of the atom. Size of a nucleus is extremely small as compared to the overall size of ...
Due to fall of electron from higher to lower energy level, the difference in energy is emitted in the form of electromagnetic radiation only because electrons can interact only electromagnetically. Class 12 Physics Chapter 12 Atoms Session 2024-2025.
Total length of an orbital path of electron in nth state of atom should be in times (where n is an integer), the value of de-Broglie wavelength λ.. Thus, 2πτη = η λde. Class 12 Physics Chapter 12 Atoms Session ...
