If an orbital that penetrates into will be closer to the
nuclues and it will less shilded
On the other hand an orbital that doesn't penetrate will be more
shielded
farther the orbital , greater the energy

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...

Classify each statement about effective nuclear charge, Zeff, as true or false. True False Effective nuclear charge is dependent on the number of electrons present in an atom. In a N atom, a ls electron has a greater Zer than a 2s electron. Electrons in a p orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. Als electron in a B atom has a smaller Zeff than a ls electron in a...
