this is for part b
30 points total) Potassium ferrocyanide is the inorganic compound with formula Fe(CN) 3.0. This salt forms lemon-yellow monoclinic crystals. Potassium ferrocyanide finds many niche applications in industry. It and the related sodium salt are widely used as anticaking agents for both road salt and table salt. Potassium ferrocyanide is used in the production of wine and citric acid. Potassium ferrocyanide is nontoxic, and is not decomposed to cyanide in the body. The toxicity in rats...

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...
