![]() The names of the shell are given as K, L, M, N, etc., or 1, 2, 3, 4, 5, etc. These are fixed tracks and the number of electrons that can be accommodated in a single shell also differs. Shell: The circular path taken by the electrons around the nucleus is known as shell or orbit.The Bohr-Rutherford model postulates that the electrons revolve around the nucleus in predetermined circular orbits. Electrons: These are the negatively charged species that revolve around the nucleus of the atom.They are also responsible for many physical properties of the atom. Neutrons: These are present in the nucleus along with protons and are responsible for the stability of an atom.They were named by Ernst Rutherford and are denoted by the symbol p +. Protons: These are the positively charged particles located in the nucleus of the atom.It is composed of positively charged protons and neutral neutrons. Nucleus: The positively charged body that lies at the center of the atom is known as the nucleus.The terms used in the Bohr atomic model are given below: ![]() To understand the Bohr model of the atom we must first recognize the atomic particles and their relevance in the atomic structure. It illustrates the number as well as the location of all the atomic species inside an atom. The Bohr model is a representation of the atomic structure along with all the atomic particles in pictorial form. The Bohr-Rutherford model was given in 1913 after incorporating the findings of Niel Bohr in the already given Bohr model.
