(a) Interpretation: The element that is least reactive in group 1 is to be stated. Concept Introduction: Reactivity of an element depends on its size, ionization energy, number of valence electrons in the atom. On going down the group, the reactivity of the elements increases in case of metals and decreases in case of nonmetals. This unusual trend is because of the reactivity difference in metals and nonmetals.
