Study the following part of periodic table chart and use it to answer the question that follow. The letters are of the actual symbols of the elements.


(i) Which elements form ions with charge of -2. Explain.

(ii) Compare the ionic radius of C and E. Explain.

(iii) Write the formular of the compound formed between element G and H.

(iv) In terms of structure of bonding, explain why the oxides of D has a lower melting point than that of G.

(v) Write an equation to show the action of heat on nitrates of F and G.

---

(i) A or D

(ii) E has got smaller atomic radius than C, because across the periodic there is an extra-added nuclear charge in the nucleus which strongly pull the valence electrons in E in C, thus reducing it s atomic radius.

(iii)G²⁺ x H^-1

GH₂

(iv) Oxide of D has a weak covalent bond within its structure, with simple molecular structure, while that of G has strong ionic / Electrovalent bond with Giant ionic structure.

(v)
