Niels bohr niels bohr atomic model3/21/2024 ![]() ![]() The atom, on the whole, is electrically neutral due to an equal number of negative electrons and positive protons. ![]() – Electrons possess a negative charge, neutrons have no charge, whereas protons have a positive charge. An atom comprises three particles, i.e., neutrons, protons, and electrons. In contrast, it will have less energy if situated near the nucleus. Bohr concluded that an electron would have more energy if it is far from the nucleus. However, to account for the stability of the atom, he introduced the concept of the stationary orbit.īohr’s Atomic model explains that a small positively charged nucleus is surrounded by negatively charged electrons revolving in fixed orbits. Experimental results of atomic spectra can explain only by assuming quantised electronic energy levels in atoms.īohr retains the essential features of the Rutherford model of the atom.The dual personality of electromagnetic radiation means that radiations possess particle-like and wave-like properties.Two developments played a major role in formulating the Bohr model of the atom. Let’s have a look at Bohr’s atomic model. Quantum mechanics serves as the foundation for the contemporary model of an atom. In 1913, Neil Bohr put forward an atomic model based on Planck’s quantum radiation theory. To remove the drawbacks of Rutherford’s nuclear atomic model and explain the origin of the production of the spectrum of Hydrogen and Hydrogen-like species (such as Li 2+, He +, etc.). ![]()
