They have only one electron shell characteristic(s) they share that determine(s) their position, hydrogen and helium are the only elements in the first row of the periodic table.

The electron is a subatomic particle because it has an elementary electric charge that is negative. Electrons, the first generation of the lepton family of particles, are usually considered to be elementary particles due to their lack of components or substructure.Many physical processes, such as gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity, depend on electrons.The atomic number of an element is equal to the number of electrons present in an atom for neutrally charged species. This shows that an element has the same number of protons and electrons as other elements. Consequently, oxygen has 8 electrons.Charge, spin, and orbital angular momentum are the three primary properties of an electron in an atom. The latter term defines the
