The atomic orbitals are progerssively filled in order of increasing energy. The principle is called as :

The atomic orbitals are progressively filled in order of increasing energy. This principle is called:

The word 'aufbau ' in German menas 'building up' . The building up of orbitals the filling up of orbials with electrons. In the ground state of the atoms, the orbitals are filled in order of is their increasing energies. In unielectron species, energy is determined by 'n' but in multielectron species, energy is determined by n + l value . Answer the following question on the basis of above paragraph : (a) State Aufbau principle . (b) Out of 4f and 5s electron orbitals, inbitals, indicate which of higher energy ?

The correct order of increasing energy of atomic orbitals is

The correct orders of increasing energy of atomic orbitals is

The correct orders of increasing energy of atomic orbitals is

Which principle is stated that the orbitals are filled in the order of increasing energy ?
