Heaviest elements yet join periodic table

The periodic table of the elements is a list of known atoms (chemical elements). In the table the elements are placed in the order of their atomic numbers starting with the lowest number. The atomic number of an element is the same as the number of protons in the atom.

There are heaps of online periodic tables that give you information on all the elements, some even include videos.

Of the 118 known elements, only the first 94 are believed to occur naturally on Earth. The other ones have been synthesized by scientists.

Elements 114 and 116 have been officially added to the periodic table, becoming its heaviest members yet. They both exist for less than a second before decaying into lighter atoms, but they bring researchers a step closer to making even heavier elements that are predicted to be stable for decades or longer, forming a fabled “island of stability” in the periodic table.
