Detailed explanation-1: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
Detailed explanation-2: -electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge.
Detailed explanation-3: -An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom–the other two are protons and neutrons. Together, electrons, protons and neutrons form an atom’s nucleus.
Detailed explanation-4: -Electrons are negatively charged subatomic particles found in the outermost regions of atoms.
