“Aufbau Policy explanation” very important for Chemistry student
Aufbau Principle: Electrons first enter the low energy orbital and then gradually enter the high energy orbital. Explanation: From the diagram above :- 1s<2s<2p<3s<3p<4s<3d<4p<5s – – – – – Or 1s22s22p63s23p64s23d104p65s2s2 Thus entering the e-orbital. (n + l) Rule: The orbital which is less than the value of (n + l) is the lower energy […]
