What's the answer..???

Question

For every element, less energy is needed to remove an electron from a neutral atom than is needed to remove another electron from the resultant ion. Explain why..

Answer 1

shielding effect. and the process you're talking about is ionization and ionization energy. ill try to explain..
say u have 5 protons in the nucleus and 5 electrons and the charges "cancel out". u take an electron away and now its 5-4
the pull the protons have on the electrons will be stronger and will take more energy to take another electron
