Question

die ullerelt With dlnerent 2. That means, if you have two isolectronic species, such as Ca2+ and s?-, both of which have electronic configurations of lAr, Ca? will be the smaller because it has more protons than S2-. Which of the following statements is false? O higher nuclear charge lowers orbital energy (stabilizes the system) by increasing nucleus-electron attractions for a given n value, the lower the l value, the higher the subshell energy O "penetration" by an ns electron increases its overall attraction to the nucleus relative to that for an np electron, thereby rendering subshells ns and np with differing energies O inner electrons shield outer electrons y than do electrons in the same subshell, so shielding by inner electrons greatly lowers the Zar felt by outer electrons "shielding" reduces the full nuclear charge to an "effective nuclear charge" (Z. 0.2 pts Question 20 ave the largest atomic radius Which of the following atoms is predicted to h
