In a xenon atom, which atomic shell would experience the largest effective nuclear charge?

Answer;

1 s

Explanation;Xenon is a chemical element with an atomic number 54, which means it has 54 protons in the nucleus and 54 electrons in the energy level since the number of electrons in an atom is equal to the number of protons.Xenon has an electron configuration of 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6. The orbital or energy shell closest to the nucleus experiences the largest effective nuclear charge as compared to the other orbitals or energy levels.Therefore, the answer would be the 1s orbital, it is closest to the nucleus and thus experiences the largest effective nuclear charge.
