Question

Which diagram enables us in finding the ascending order of ( n + l) value.​

Answer 1

n + l value (MOELLER'S DIAGRAM):

• The (n + l) value of atomic orbitals helps to arrange the various orbitals in an ascending order with respect to their energy content.

• 'n' is the PRINCIPAL QUANTUM NUMBER and 'l' is the AZIMUTHAL QUANTUM NUMBER.

• Higher (n + l) value corresponds to higher energy content.

• The diagram which helps us to understand this order of orbitals is attached as a photo.
