Web12 sep. 2024 · Figure 8.2.1: A representation of the Bohr model of the hydrogen atom. With the assumption of a fixed proton, we focus on the motion of the electron. In the electric field of the proton, the potential energy of the electron is. U(r) = − ke2 r, where k = 1 / 4πϵ0 and r is the distance between the electron and the proton. WebEach atom has a charged sub-structure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. The number of protons and the mass number of an atom define the type of atom. Atoms of the same element with different mass numbers are called isotopes. Created by Jay.
