Following statements regarding the periodic trends of chemical reactivity of the alkali metals and the halogens are given. Which of these statements gives the correct picture?
View answer and explanation
Correct option: D
In alkali metals the reactivity increases but in the halogens it decreases with increase in atomic number down the group.
Option D is correct because the reactivity of alkali metals increases down the group due to decreasing ionization energy, while the reactivity of halogens decreases down the group due to decreasing electronegativity and electron affinity.
