Understanding the Answer
Let's break down why this is correct
Reaction with hydrogen produces solid metal hydrides and is the slowest reaction. Other options are incorrect because Some think oxygen is the most reactive because it is essential for life, but for alkali metals it needs heat to react; Halogens are often thought to be the strongest because they are very reactive gases, yet water causes a much larger reaction with alkali metals.
