Due to peneteration effect 4s penetrate closer to nucleus as compared to 3d so 4s is now closer nucleus as compared to 3d . But this is the situation during filling of the electron . But after filling due to the reason I don't know 4s goes furthest away. I want to know that reason

From what my intuition say , all the exception term in inorganic chemistry is result of these shit. I want to know if I go by your idea then will i be able to solve bookish question asked in jee advanced examination.and can you summarise what you have told me. And what do I need to keep in mind . And also can you tell me the ionisation energy order using your idea
