This is the reason ideally the electrons are bounded and moves in the orbital path. Due to this attractive force, the electrons and protons are attached within the atom. As electrons and protons hold the same charge of opposite polarity thus there exists a force of attraction between them inside the atom. As the nucleus holds both protons and neutrons thus combinedly called nucleons. It is denoted by a symbol p and has a charge +1.Ī noteworthy point over here is that the number of protons that are present in an atom signifies its atomic number. As the nucleus of the atom is at the center thus a proton holding a positive charge is present at the center of the atomic structure. It’s a crucial component of an atom that forms the nucleus of an atom with the neutron. Proton is another major particle of an atom with a charge of positive polarity. And all the electrons are considered to be identically similar to each other. The electron charge is measured in Coulomb and has a value of about 1.602 * 10 -19 C. And an electron is considered to have a unit electrical charge generally represented as e. In the case of conductors, the movement of electrons is the reason for the flow of current. While when external energy is supplied to the electrons then they move from an atom to another.īasically, the energy supplied to the electrons frees them from the shells thus they become mobile and get attached to its nearby atom whenever there is a deficiency of electron in that particular atom. Inside an atom, ideally, electrons are present in spherical shells and move around the nucleus in an orbital path. These are very difficult to get added or removed.Ī subatomic particle of an atom that holds an electric charge of negative polarity. These can be easily removed from or added to an atom. Outside the nucleus in a well-defined orbit. Therefore, has various differentiating factors which we will discuss here. Among electron, proton, and neutron, the electrons and protons are negatively and positively charged respectively while the neutrons are neutrally charged particles.Įlectrons and protons hold different properties and are present at different locations inside the atom. The electric charge of the atom maintains the bond between the atoms in a molecule. Multiple atoms form a molecule and the atoms inside a molecule are attached by chemical bonds. While this atom itself has 3 major subatomic particles which are known as electron, proton, and neutron. We know that an atom is regarded as the smallest particle as it is the fundamental unit by which a matter is composed.
