The most dangerous elements on the periodic table - Shannon Odell · 4:39 · Video: TED-Ed · Watch at the source

In short: Shannon Odell explores the most hazardous substances found in the periodic table. This video examines why certain elements are dangerous, categorizing them by their toxicity, their volatile reactions with the environment, and their ability to silently emit energy.

The periodic table contains a variety of elements that present significant risks. Some are inherently toxic, while others are classified as dangerous due to their tendency to react violently or explode when exposed to the outside environment.

Beyond chemical reactivity and toxicity, the most threatening elements are those that emit energy silently. This video provides an investigation into these categories to identify which specific substances are the most hazardous.
