Text Solution

Verified by Experts

(i) Eka-silicon is germanium (Ge). It lies in group 4 of the Mendeleev.s periodic table and thus, has a valency of 4. The formula of its chloride is `GeCI_4`.
(ii) Eka-aluminium is gallium (Ga). It lies in group 3 of the Mendeleev.s periodic table and thus, has a valency of 3. The formula of its chloride is `GaCI_3`.
