Document Summary
Jim and tim"s excellent adventure"s in final exam preparation. Which of the following statements is a true statement about the orbital into which the last electron was filled for the element. It absorbs enough energy so that its final energy is greater than zero. Practice final #1 - 2013: the ionic radii of the ions, fe2+ and fe3+, are different. Which of the two has the larger radius and why: fe3+. Although both the species have the same nuclear charge, more electrons are pulled in the case of fe3+ than in fe2+: neither fe2+ nor fe3+, but fe+1 has the larger ionic radius. Since the removal of only one valence electron from its outermost d orbitals, the species acquire a d5 configuration and thus give a greater stability to fe+ cation (half-filled orbitals are as stable as the filled ones): fe2+.
