Homework Answers
Shielding effect is the prevention outer electrons from feeling the nuclearcharge by the inner /core electrons.
Thus First one is correct .
The core electrons also repel with each other and at the same time feel the attraction of the nucleus.
Thus they among themselves also feel the shielding effect.
Thus 2nd one is also correct.

Classify each statement about penetration and shielding as true or false. Assume all lower-energy orbitals are fully occupied True False Answer Bank An electron in an orbital that penetrates closer to the nucleus will always experience more shielding than an electron in an orbital that does not penetrate as far.

1. Which element has larger Effective Nuclear Charge? Li or K I thought it would be Li because it has 2s1 as valence electron and this is closer to the nucleus with less shielding...would this not be the one with the highest effective nuclear charge. the answer says that its K which has a higher nuclear charge and this charge is countered by shielding of the core electrons but wouldn't K have a lower effective nuclear charge as it is...
