Electrons are subatomic particles that hold an elementary charge of magnitude -1. The charge of an electron is equal in magnitude to the charge held by a proton (but has an opposite sign). Therefore, electrically neutral atoms/molecules must have an equal number of electrons and protons. Although the magnitude of the charges held by protons and electrons are the same, the size and mass of an electron are much smaller than that of a proton (the mass of an electron is roughly 1/1836 the mass of a proton). Owing to their small size and mass, the properties exhibited by electrons can be studied better with the help of quantum mechanics rather than classical mechanics. This is because matter behaves differently at the quantum scale. For example, the uncertainty associated with the position and the velocity of an electron is much greater than that associated with a proton or a neutron, as per Heisenberg’s uncertainty principle. Electrons are distributed around the nuclei of atoms in atomic orbitals, which can be simply visualized as regions around the nucleus in which the probability of finding a specific electron is the highest.
