Question

explain the relative energies of atomic orbital​

Answer 1

Answer:

I hope this explanation will be enough.

Explanation:

Relative energies of atomic orbital is

we have s,p,d,f orbital for the shell 1,2,3,4

1s subshell have lowest relative energy so, electron must fill this shell first. The 2s orbital have 2nd lowest relative energy, so must therefore be filled second, followed by the 2p subshell.

Answer 2

The relative energies of the atomic orbitals are in the order: s < p < d < f.

• s-orbitals are spherically symmetrical in shape. Hence, they experience a uniform force of attraction from the nucleus. This results in a greater degree of attraction and lowers their relative energy.
• p-orbitals have two lobes. The probability of finding an electron is more than the other orbitals but less than s-orbitals. Hence, due to relatively high negative charge possessed by them, the nucleus attracts them more than d and subsequently f-orbitals.
• Therefore, the energies of the atomic orbitals are in the order of s < p < d < f based on the quantum mechanical model.
