The Universe

Updated: Aug 28, 2019

When the universe was born, there was a great deal of energy and particles zooming about, crashing into one another. Different elements were made as clusters of protons and neutrons formed the nucleus of atoms. A periodic chart lists most of the stable elements found in nature. Physicists have complicated this natural process by exposing some elements to high velocity particle blasting. A whole class of new elements have been made using this process. They don’t always last very long, though! Some elements like, Organesson, lasts only 1/1000 of a second before it decays into something else. Nobelium 259 lasts about an hour. Examine the chart of these unstable elements and note that the range of life from extremely short to as long as the origin of the universe.
