What is #44: Uranium?

The last post in this series looked at iron, the last element on the periodic table that is the result of fusion in the core of a star due to it having the lowest mass per nuclear particle. Today we take a look at Uranium, element number 92.

Uranium is used as nuclear fuel on Earth. In the Universe, it is produced in very high energy events. This possibly includes a supernova, but more likely requires an even higher energy event such as the collision of two neutron stars.

There are more elements heavier than Uranium on the periodic table, but Uranium is the last, by mass, of the naturally produced elements. All elements heavier than Uranium were created in labs on Earth by humans.

Uranium has many uses on Earth and is the last of the naturally produced elements on the periodic table. Now you know!
