Rather, their position can be described as a wave function.
After filling the first shell level (with just an s subshell), electrons move into the second-level s subshell and then into the p subshell before starting on another shell level.
Though electrons are often represented as particles in discreet orbits around the nucleus, they cannot be said to occupy a specific point in space. Electrons are grouped in distinct "shells" located outside the nucleus; each shell holds a limited number of electrons, and the number depends on the type of shell. Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. Because the charge of electrons is opposite in sign than protons, the two types of particles attract each other, and this force, known as the Coulomb force, holds the atom together. Though the electron shell is the only stable location for electrons, a heavy atom that undergoes beta decay can emit an electron from its nucleus. In most atoms, electrons occupy a zone exterior to the nucleus. The exterior shell of the atom is not the only place electrons can be found in an atom. In most atoms, electrons occupy a zone exterior to the nucleus. Will 5G Impact Our Cell Phone Plans (or Our Health?! Festival of Sacrifice: The Past and Present of the Islamic Holiday of Eid al-Adha, MEHAU KULYK/Science Photo Library/Getty Images. Rather, their position can be described as a wave function.
The electron shells are relatively far from the nucleus, making the atom more than 99 percent empty space.

To avoid confusion, electrons emitted by the nucleus are referred to as beta particles. Fact Check: What Power Does the President Really Have Over State Governors? https://www.wikihow.com/Find-the-Number-of-Protons,-Neutrons,-and-Electrons Electrons fill in shell and subshell levels in a semiregular process, as indicated by the arrows above. Though electrons are often represented as particles in discreet orbits around the nucleus, they cannot be said to occupy a specific point in space.
