surrounds the nucleus of an atom in various energy levels called orbitals.
Explanation:
Electrons surrounds the nucleus of an atom in various energy levels called orbitals.
According to the Bohr's model of an atom, the extra nuclear space is made up of electrons in specific spherical orbits called shells or energy levels.
- The region of a maximum probability of where an electron is located is sometimes referred to as an electron cloud or orbital.
- Electrons move round the nucleus in certain permissible orbits.
- An electron in an energy level posses a definite amount of energy associated with it at that level.
- Electrons moves through the energy levels by gaining or losing energy.
