Question

When filling orbital with electrons wefill according to Diagonal filling rulefill up s orbitals, then p orbitals, then d orbitalsfilling according to electrons spinfill each energy level before moving up

Answer 1

Step-by-step explanation:

Orbitals are filled according to the aufbau principle. That is, lower energy orbitals are filled before higher energy orbitals are filled. Therefore, fill each energy level before moving up

Answer:

The second last option is correct.
