Question Video: Identifying the Most Reactive Metal from a List of Five Metals Science • Second Year of Preparatory School

Video Transcript

Consider the following metals: silver, sodium, magnesium, calcium, and iron. Which of those metals is the most reactive?

We need to find which metal is the most reactive. We can do this using the reactivity series. The series mostly consists of metals, and the reactivity of the species increases upon ascending the list. If we find all of the elements given in the question, we can see that sodium is the closest to the top of the series.

Therefore, the most reactive of the metals given in the question is sodium.
