An extended periodic table theorizes about chemical elements beyond those currently known and proven. the element with the highest atomic number known is oganesson ( z = 118), which completes the seventh period (row) in the periodic table. all elements in the eighth period and beyond thus remain purely hypothetical. In that respect, even new elements aren't always directly discovered. in some cases, insufficient amounts of the elements have been synthesized for us to know what the element looks like. yet, the elements are considered to be known, are named, and are listed on the periodic table. there will be new elements added to the periodic table, but.

And it may also be that the current upper end of the periodic table is just another such gap, beyond which may exist an island of stability containing useful elements never before encountered. This has led scientists to speculate that there are naturally occurring, stable elements out there beyond the periodic table – even beyond the unstable, radioactive superheavy elements between atomic numbers 105 and 118, which have only ever been observed in laboratory settings. it's unknown whether elements with more than 118 protons would.

If you wanted to create the world’s next undiscovered element, number 119 in the periodic table, here’s a possible recipe. take a few milligrams of berkelium, a rare radioactive metal that can. An element is by definition identified with the number of protons in its nucleus, the so called atomic number. any atom with 6 protons is carbon, it cannot be anything else. so there cannot be any missing elements out to 103, as all of these elements have been confirm discovered by accepted scientific methods.
