Question: What is the most powerful element on the Planet Earth?

Michael Nolan answered on 15 Nov 2013:

Not sure what you mean here, there are a few ways to answer this…

The heaviest naturally occurring element in Uranium (number 92)

The most stable is iron

The most explosive are the alkali metals: lithium, potassium, cesium and francium (arises since they have one electron that they like to give away and when they do that there is a huge amount of energy released; see my answer on lithium-water interaction)

The least stable is francium

So perhaps the best answer to your question is Francium

hope this helps
