Question

define the term degenerate orbitals?

Answer 1

Electron orbitals that have the same energy levels are called degenerate orbitals. When assigning electrons to orbitals in determining electron configurations, the Aufbau principle states that lower energy orbitals are filled before higher energy orbitals.

Answer 2

in absence of an external electric field or in presence of a spherical symmetric electric field the orbitals are degenerate that means they have same energy level
