Answer:
(a) Li, K belong to group 1. They are both alkali metals.
(b) Magnesium (Mg) has a valency of two. Being electropositive, it has a tendency to lose two electrons to attain a stable octet.
(c) Carbon (C) is tetravalent (4 valence electrons) and prefers to share electrons.
(d) K (potassium) is the most metallic element, as it is on the left hand side and below Li, the second most metallic element here. It is also very reactive.
(e) Sulphur (S), and Carbon (C), being non-metals form acidic oxides SO2 and CO2.
(f) Aluminium (Al) belongs to group 13.
