Question

state the order of filling atomic orbitals following aufbau principle.???????​

Answer 1

Answer:

it is based on n+l rule the suborbital have les n+l will filled 1st and if n+l is same of two sub orbitals then suborbital with small n will be filled 1st.

Answer 2

Explanation :

According to the Aufbau principle, the atom or ion that present in the ground state, the lowest energy level will be filled first before occupying the higher levels.

For example : The 1s shell will be filled first before 2s subshell.

According to this principle, the highest energy orbital will have the higher value of (n+l) where 'n' is azimuthal quantum number and 'l' is angular quantum number.

The order of filling atomic orbitals are shown below.
