Which element is the most reactive metal?
Understand the Problem
The question is asking for the identity of the most reactive metal element on the periodic table. This involves understanding the trends in reactivity among metals, particularly focusing on alkali metals which are known for their high reactivity.
Answer
Francium, practically cesium
The most reactive metal is francium, but due to its scarcity and radioactivity, cesium is considered the most reactive metal in practical terms.
Answer for screen readers
The most reactive metal is francium, but due to its scarcity and radioactivity, cesium is considered the most reactive metal in practical terms.
More Information
Francium is the most reactive metal but is rarely encountered due to its radioactivity. Cesium, which is more commonly used in experiments, is almost as reactive.
Tips
A common mistake is not distinguishing between theoretical reactivity (francium) and practical reactivity (cesium).
