Answer:
When 3d orbitals are filled, 4s is no longer lower in energy. Hence electrons are lost from 4s orbital first, because electrons lost first will come from the highest energy level (furthest away from the nucleus).
Verified answer
Answer:
madam I know this one only
Explanation:
Yes ....becuase of aufbau's principle ..... 3d orbitals come before 4s orbitals.....and also we know that if 3d orbitals fill ...
the next orbital to fill is 4s .... So 4s in no longer low in energy and the statement you told is correct........this is the answer I know....I don't know it's right or wrong .... if it is right ....you can mark me as brainliest....and if it is wrong .....please give me 1 star rating...............
Thanking you
