Two fold degeneracy

Web(a) In some cases, we have n-fold degenerate ground sates (e.g. the alkali metals, have a 2-fold degenerate ground state, corresponding to two orientation of the electronic spin). In such cases, the partition function is equal to the degree of degeneracy, i.e.: (b) In some cases, there are low-lying electronically excited states. WebIn presence of magnetic field, the degeneracy of orbitals remains the same if the orbitals can be inter converted by symmentric operation like rotation, reflection etc. Since p …

Due to this, in presence of magnetic field also, the p-orbitals are three-fold degenerate. In covalent bonding, two atomic orbitals can collaborate to generate two “hybrid orbitals”. The hybrid orbitals have two energy levels.
