Electrons, protons, and neutrons are the three fundamental particles in an atom. Electron is a negatively charged particle, and according to Dalton's Atomic Theory, electrons are found outside the nucleus, and they orbit the nucleus. Protons, on the other hand, are positively charged particles found inside the nucleus of an atom together with neutrons. Protons consist of other simpler particles, while electrons do not consist of other simpler particles. Since both protons and neutrons have opposite charges, electrons will always revolve around the nucleus in a bid to get attracted to a proton.

And since the number of electrons in an atom is equal to the number of protons, therefore, we have a neutral atom. Electron is usually represented with the symbol e-, while a proton is represented with the symbol p+. The relative mass of an electron is 0.00055, whereas the relative mass of a proton is 1. The atomic number of an atom can be calculated by knowing the number of particles or protons in a molecule.

Electrons are a particle that have a negative charge. They usually have a mass of about 9.10938356 x 10-31 kilograms. Electrons can be found in cells where they transport or donate energy to the acceptors. They can also be found in electricity and gravitational forces and interactions. Surrounding the electron is an electric field. Electrons attract the protons because protons have a positive charge. Protons are also particles. AMU stands for atomic mass unit and the protons weight about one AMU. Neutrons also weigh about one AMU.

The mass of the proton is about 1.6726 x 10-27 kilograms. Each nucleus is made up of both protons and neutrons. Electrons are not found as part of the nucleus. The electron has a charge of negative one and the opposite for proton. They have a positive one charge.

An opposite charge and a smaller mass.

Protons are positively charged and have a mass of 1.00720 amu; electrons are negatively charged and have a mass of 0.00055 amu. See Table O for further information.
