Work Step by Step
Hydrogen orbitals and multielectron atom orbitals share certain similarities.
(1)The energy levels of the orbitals of multielectron atoms are different from those in hydrogen orbitals, and they govern the amount of energy needed for an electron to travel from one orbital to another.
(2)The primary quantum number, which controls the size and energy of the orbital, is a characteristic of both hydrogen orbitals and the orbitals of multielectron atom
Differences between the orbitals of multielectron atoms and hydrogen orbitals:
In multielectron atoms, the presence of more than one electron leads to the repulsion between electrons, which causes the energy levels of the orbitals to split into sublevels. This results in the degeneracy of orbitals with the same principal quantum number, which is not observed in hydrogen.
The presence of more than one electron also results in the formation of electron-electron correlation, which causes the shape of the orbitals to deviate from the simple spherically symmetric shape of hydrogen orbitals. As a result, the orbitals of multielectron atoms can have complex shapes and can even exhibit nodal planes where the probability of finding an electron is zero.
