Following statements regarding the periodic trends of chemical reactiv...
The alkali metals are highly reactive because their first ionisation potential is very low and hence they have great tendency to loses electron to form unipositive ion.
NOTE : On moving down group- I from Li to Cs ionisation enthalpy decreases hence the reactivity increases. The halogens are most reactive elements due to their low bond dissociation energy, high electron affinity and high enthalpy of hydration of halide ion.
However their reactivity decreases with increase in atomic number

Following statements regarding the periodic trends of chemical reactiv...
Explanation:
Alkali Metals:
- In alkali metals, as we move down the group from lithium to francium, the reactivity increases.
- This increase in reactivity is due to the decrease in ionization energy and increase in atomic size down the group.
- The outermost electron in alkali metals is easily lost to form a positively charged ion, which is why they are highly reactive.
Halogens:
- In halogens, as we move down the group from fluorine to iodine, the reactivity decreases.
- This decrease in reactivity is due to the increase in atomic size and decrease in electron affinity down the group.
- Halogens are highly reactive non-metals that readily gain an electron to form a negatively charged ion.
Comparison:
- The statement that "In alkali metals the reactivity increases but in the halogens it decreases with increase in atomic number down the group" is correct.
- This is because alkali metals lose electrons to achieve a stable electron configuration, while halogens gain electrons to achieve the same.
- Therefore, alkali metals become more reactive as the outermost electron is farther away from the nucleus, while halogens become less reactive as it becomes harder to gain an additional electron.
