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...

Predicting lonic Compound Formulas Activity Ionic compounds are compounds composed of two substances which have a preferred ionic charge. The number of each type of compound must be balanced so that the ionic charge of the combination is zero, and the positive and negative charges balance. For each of the compounds below, you must interpret the name of the ionic compound using the naming rules to decide what elements or polyatomic groups make up the compound. Using the information on...
