Question

1) Rank these elements in order of increasing ionization energy (least IE first, to the left; most IE last, to the right). Explain your ranking in terms of the behaviors of metals, the behaviors of nonmetals, the behaviors of noble gases, effective nuclear charges, and the distances of outer shells from the nucleus:: Zn, Ca, Kr, I 2) For each of the following species, a) indicate the number of shells it has b) Rank them in order of increasing radius (smallest, first, to the left; largest, last, to the right). Explain your ranking in terms of the behaviors of metals, the behaviors of nonmetals, the behaviors of noble gases, effective nuclear charges, and the numbers of shells: Li, C, F, I-, Li+, I

Explanation / Answer

1) As krypton is a noble gas ,it has the highest ionization energy. Iodine(I), then Calcium(Ca) , then Zinc(Zn) , then Krypton(Kr). 2) Radius- I
