Bohr
NettetCalculate the wavelength of an electron moving with a velocity of 2.05×10 7ms −1. The uncertainty in the momentum of an electron is 1.0 × 10 −5 kg m s −1. The uncertainty of its position will be: A golf ball has a mass of 40 g, and a speed of 45ms −1. If the speed can be measured with in accuracy of 2%, calculate the uncertainty in ... NettetLimitations. According to Danish physicist Niel Bohr’s atomic model, an atom includes a small, charged nucleus surrounded by electrons that journeys in round orbits across the nucleus with force supplied through electrostatic forces. This version of Bohr’s theory was entirely based on Planck’s quantum principle of radiation. lane community college tuition 2022

NettetThings to Remember. Bohr’s atomic model postulated the presence of a positively charged nucleus at the centre of the atom surrounded by electrons travelling in a … Nettet25. jan. 2024 · Bohr’s model of atom suffers from the following limitations. Bohr’s theory fails to explain the line spectra of multielectron atoms. It does not explain the splitting of spectral lines into a group of finer lines under the influence of magnetic field (Zeeman effect) and electric field (Stark effect). NettetDrawbacks of Bohr's atomic model: He could not explain the details of the Hydrogen and Helium atomic spectrum. He did not explain the splitting of spectral lines in presence of a magnetic field. The intensity of spectral lines was not explained by him. He could not explain the Zeeman effect i.e. splitting of spectral lines in Magnetic field as ... hemodialysis risk for infection
