Researchers may have found a way to create a new superheavy element, known as "element 120," which would be so hefty that it would need to be put in a new row on the periodic table of elements. If they can create this hypothetical element, its atoms could represent an "island of stability" that could revolutionize heavy-element chemistry.
There are currently 118 known elements listed on the periodic table; from hydrogen, which has a single proton in its nucleus, all the way up to oganesson, which was officially named in 2016 and has at least 294 subatomic particles packed into the centers of its atoms (118 protons and at least 176 neutrons).
