2. It is possible to divide elements into groups according to their electron configurations. The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling, and the inner transition metals are the elements where the f orbitals are filling. (a) Like first member of other groups, carbon also differs from rest of the members of its group. Give two (2) properties that were only own by carbon, and not the other members of its group. [2 marks]
(b) Diagonal effect is a phenomenon where two elements from adjacent groups show greater similarity than is observed between these elements and the members of their own respective groups. Give two (2) similar properties shared by the diagonal effect pair of beryllium and aluminium. [2 marks]
