Both oxygen gas and water must be present for the iron to rust. While sodium reacts spontaneously and violently with air and cold water, magnesium reacts with air less vigorously and with water when heated. Its sym­bol is Fe. Theoretically, they are all capable of displacing hydrogen from water, but that doesn't happen. When a metal reacts with water, a metal hydroxide and hydrogen are formed. The reaction makes it hot enough to melt into a silvery ball. Still have questions? In general, the more reactive the metal, the more rapid the reaction.

Magnesium, being an alkaline earth rare earth (s-block) metal, reacts with water more actively than most other transition (d-block) metals such as iron, copper, zinc, etc do. If allowed to continue, the oxygen and water will completely convert the remaining iron to ferric oxide (or solid rust), which is weak and flaky, hence big holes in metal (cancer). It reacts with dilute hydrochloric acid. This displacement of hydrogen from water is what happens during rusting. Also some group 2 elements GROUP 1 All of these metals react vigorously or even explosively with cold water. Relevance.
