orbitals are fully occupied.
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. An electron in a 2s orbital penetrates into the region occupied by...

Consider the following information for sodium and chlorine: Atomic radius: Na (186 pm) and Cl (100pm) Ionic radius: Na+(102pm) and Cl-(181pm) Why does the atomic radius decrease while ionic radius increase? The outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. Monatomic ions are bigger than the atoms from which they are formed. The outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. The...

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...
