The table below shows elements A, B, C, E, F, and G. Elements in group X have a valency of 2 while elements in group Y have a valency of 1. Use the table to answer the questions that follow:-

(i) Atomic radius increases from A to C and from E to G. Explain
(ii) Explain the difference in the atomic and ionic radii of group X elements
(iii) Elements C and G belong to the same period. Explain why the atomic radius of C is
greater than that of G
(iv) Give the formula of the compound formed when B and F react
(v) What type of bonding is formed in the compound above? Explain
(vi) Starting with the least reactive, arrange the elements in group Y in the order of reactivity.
Explain:

---

(i) Down the group an extra energy level is added

(ii) In group x elements form ions by ionizing the outer energy levels

(iii) A cross the period an extra proton is added which increased he nuclear attraction force

(iv) BF₂

(v) – Ionic /electrovalent
- Involves loosing & gaining of electrons

(vi) G, F,E
-E has smallest atomic radius hence protons can attract an electron easier than in G
