How many elements are undiscovered
WebAn 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. WebFour new elements have just been added to the periodic table completing the table’s seventh row. But despite elements 113, 115 and 118 all being discovered in the early 2000s and 117 in 2010, there’s still no sign of elements 119 and beyond.
