Question

effective nuclear charge of pb=?​

Answer 1

Answer:

3 electrons

Krypton has a larger nuclear charge (Z=36) than argon (Z=18). The shielding of the n=3 shells by the 1s and 2s electrons in the two atoms is approximately equal, so the n=3 electrons in Kr experience a greater effective nuclear charge and are thus situated closer to the nucleus

Answer 2

Answer:

Effective Nuclear Charge. 60.4300
