Group 1 metals react instantly with _____ causing flames/explosions/fizzing whereas magnesium takes several days to produce hydrogen gas

Group 1 metals, also known as alkali metals, react instantly with water, causing various reactions that can lead to flames, explosions, or fizzing. When these metals come into contact with water, they form hydroxides and release hydrogen gas. The reaction is highly exothermic, and in some cases, the heat generated is enough to ignite the hydrogen gas, resulting in flames or explosions.

In contrast, magnesium reacts with steam or hot water more slowly than alkali metals do with cold water. This slower reaction can sometimes take several days to produce significant amounts of hydrogen gas compared to the rapid reactions observed with Group 1 metals. Understanding these differences in reactivity not only highlights the unique characteristics of different metal groups but also provides insight into their potential applications and safety considerations in laboratory and industrial settings.
