eli5 : is there a limit to the number of trans-uranium elements that can be in the periodic table?

409 views

Someone told me that there is a limit to the number of trans uranium elements that can be in the periodic table. His reasoning was that when the number of electrons for an element gets big enough, the electrons in the outer shell will be so far out that they will have to travel faster than the speed of light to orbit the nucleus. Could he be right?

There are known challenges to creating extremely heavy elements, and none have been observed occurring naturally. We’ve really struggled to keep the higher ones we make now stable, and prevent them from decaying down to a smaller element.

But there’s also no known reason element 200, 1,000, or 1,000,000 can’t exist. We just haven’t developed a way to create them and find out if they’re stable yet.
