![]() For example, this is an unbalanced equation: N 2 + O 2 -> NO. The law states that the quantity of each element involved in a chemical reaction does not change. “PlumPuddingModel Man圜orpuscles” By Tjlafave – Own work (CC BY-SA 4.0) via Commons WikimediaĢ.The need for balanced chemical equations is dictated by the law of conservation of mass. “Geiger–Marsden experiment.” Wikipedia, Wikimedia Foundation, 8 Nov. ![]() “Thomson atomic model.” Encyclopædia Britannica, Encyclopædia Britannica, inc., 27 Dec. “Thomson Atomic Model & its Limitations | Development Of Atomic Model.” Chemistry, Byjus Classes, 7 Nov. The main difference between Thomson and Rutherford model of atom is that Thomson model does not give details about the atomic nucleus whereas Rutherford model explains about the nucleus. Thomson model of atom and Rutherford model of atom are two models proposed by J.J.Thomson and Ernest Rutherford, respectively in order to explain the structure of an atom. Rutherford Model of Atom:Rutherford model of atom indicates that an atom has a central solid core surrounded by electrons. Thomson Model of Atom: Thomson model of atom indicates that the atom is a spherical structure. Rutherford Model of Atom:Rutherford model of atom states that electrons are located around a central solid material. Thomson Model of Atom: Thomson model of atom states that electrons are embedded in a solid material. Rutherford Model of Atom:Rutherford model of atom explains about the atomic nucleus. Thomson Model of Atom: Thomson model of atom does not give any details about the atomic nucleus. Rutherford Model of Atom: Rutherford model of atom describes that an atom is composed of an atomic nucleus and electrons surrounding the nucleus. Thomson Model of Atom: Thomson model of atom states that electrons are embedded in a positively charged solid material which is spherical in shape. Difference Between Thomson and Rutherford Model of Atom Definition ![]() Later, Rutherford model was also rejected because it could not explain why the positively charged nucleus and electrons are not attracted to each other. Hence, most of the space in the atom is empty. The volume of the nucleus is negligible when compared to the volume of the atom.The number of electrons is equal to the number of positive charges (later called protons) in the nucleus.Electrons are located outside the nucleus in orbitals at a considerable distance.This center contained the mass of the atom. The atom is composed of a positively charged center which is called the nucleus.Electrons are negatively charged particles.Thomson model of atom is described base on three main facts: Soon after the discovery of the electron, the atomic model was proposed saying that the structure of an atom is like a “plum pudding”. Thomson model of atom is the structure of an atom proposed by the scientist, J.J.Thomson, who was the first person to discover the electron. Key Terms: Alpha Particles, Atom, Electron, Gold Foil Experiment, Nucleus, Plum Pudding Model, Rutherford Model of Atom, Thomson Model of Atom What is the Difference Between Thomson and Rutherford Model of Atom However, this model was also rejected because it could not explain why the electrons are not attracted to the nucleus. It was proposed who described that an atom is composed of a central solid core which is positively charged and electrons are located surrounding this solid core. Rutherford model of atom describes the atomic nucleus and the location of electrons in an atom. But this model was rejected after the discovery of atomic nucleus. This explains that this atom is a spherical structure made out of a positively charged solid material and the electrons are embedded in that solid. This model is also known as the plum pudding model due to its resemblance to a plum pudding. Thomson model of atom is one of the earliest models to describe the structure of atoms.
