If an atom contains one electron and one proton, will it carry any charge or not?.What is the usual symbol for (a) an electron (b) a proton, and (c) a neutron?.Compare an electron, a proton and a neutron in respect of their relative masses and charges.How many times is a proton heavier than an electron?.Compare an electron and a proton in respect of mass and charge.How does a proton differ from an electron?.Difference Between Electron Geometry and Molecular Geometry.Difference Between Light Microscope and Electron Microscope.However, there are many differences between proton and electron which are highlighted in the following table − Difference between Electron and Protonīoth proton and electron are the subatomic particles of an atom which carries electric charge of positive and negative polarity respectively. The charge carried by a proton is equal to that of electrons, i.e., +1.6 × 10 -19 C and the mass of proton is equal to 1.67 × 10 -27 kg. The credit of discovery of proton goes to Ernest Rutherford, who presented that every atom has a positively charged particle in its nucleus in the year 1917. The proton is usually denoted by the symbol ‘p’. The proton lies in the nucleus of the atom which makes the nucleus positively charged. Proton is a sub-atomic particle which carries an electric charge of positive polarity. Electron is the particle which led to the explanation of several phenomena in science such as electricity, magnetism, chemical bonding, thermal conductivity, etc. The mass of an electron is 9.1 × 10 -31 kg. The negative electric charge carried by an electron is equal to -1.6 × 10 -19 C. Inside the atom, the electrons are found in the extra-nucleus of the atom and moves around the nucleus in the orbit.Įlectrons are represented by the symbol ‘e’. What is Electron?Įlectron is a sub-atomic particle which carries an electric charge of negative polarity. Although, both electron and proton are sub-atomic particles, these are also called particles of electricity because they act as the charge carrier in substances. In this article, we are going to enlist all the major differences between electron and proton. Whereas, the extra-nucleus is the space around the nucleus in which the electrons revolve around the nucleus in different orbits. The nucleus is the central part of the atom and has two subatomic particles viz. Therefore, the atom is the basic building block of the matter.Īn atom consists of two main parts viz. Protons and electrons have opposite electrical charges.According to the Electron Theory of Matter, ever matter is composed of minute particles called molecules. Since a nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus. The mass of electrons is very small compared to protons and neutrons. The relative mass of a proton is 1, and a particle with a relative mass smaller than 1 has less mass. Instead of writing their actual masses in kilograms, their relative masses are used. The masses of subatomic particles are very tiny. The nuclei of all atoms contain subatomic particles called protons and most also contain neutrons.
