- Please,please help me The incorrect order of energy of following orbitals is
The incorrect order of energy of following orbitals is
- Option 1)
3s < 3p < 4s < 4d
- Option 2)
5p < 5d < 5f < 6p
- Option 3)
7s < 5f < 6d < 7p
- Option 4)
4d < 5p < 6s < 4f < 5d

As we learned in concept
Aufbau Principle -
In the ground state of the atoms, the orbitals are filled in order of their increasing energies.
- wherein
The order of energy of orbitals is determined by n+l where n= principal quantum number and l = azimuthal quantum number
So, 6p = 6+1 = 7
5f = 5+3 = 8
5d = 5+2 = 7
5p = 5+1 = 6
Clearly, to state that 5p<5d<5f<6p is incorrect.
Option 1)
3s < 3p < 4s < 4d
This option is incorrect.
Option 2)
5p < 5d < 5f < 6p
This option is correct.
Option 3)
7s < 5f < 6d < 7p
This option is incorrect.
Option 4)
4d < 5p < 6s < 4f < 5d
This option is incorrect.
