The larger the value of '1' belonging to the same main energy, higher is the energy associated with it' Comment on this statement.

Explanation

When more than one electron is present in one main energy level, the energy of a particular elec- tron is detennined by the value of '01.' When the electron enters into p-orbital from infinite distance, it has to work tovvards a weaker force of attraction than that in case of 's-' orbital due to the screen- ing effect of the 's-' orbital belonging to the same energy level. Hence, the loss of energy is less in case of electron entering the 'p-' orbital than that entering the 's-' orbital. As a result, the electron belonging to 'p-' orbital has higher energy than that belonging to 's-' orbital. Sinularly, 'd-' orbital is associated with higher energy than that of 'p' and . the energy of the 'f-' 'orbital' is the highest provided they all belong to the same main energy level.
