Question

Which element is most reactive towards water??

Answer 1

Answer:

The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen

Answer 2

Answer:

Francium ($Fr$) is the most water-reactive element.

Explanation:

• The alkali metals ($Li, Na, K, Rb, Cs, Fr$) are the most reactive metals in the periodic table; they all react rapidly, if not explosively, with cold water, causing hydrogen to be displaced.
• Alkali metal reactivity rises from the top to the bottom of the group, so lithium ($Li$) is the least reactive and francium ($Fr$) is the most reactive. Francium, on the other hand, is a laboratory-made element that has only been synthesized in small quantities.
