Sometimes, there is an absolute limit on the number of terms an officeholder can serve, while, in other cases, the restrictions are merely on the number of consecutive terms.

Principal Quantum Number (n): n = 1, 2, 3, â¦, 8. Specifies the energy of an electron and the size of the orbital (the distance from the nucleus of. the peak in a radial probability distribution plot). All orbitals that have the same value of n. are said to be in the same shell (level).
