Meitnerium is a synthetic chemical element with the symbol Mt and atomic number 109. It is an extremely radioactive synthetic element (an element not found in nature, but can be created in a laboratory). The most stable known isotope, meitnerium-278, has a half-life of 4.5 seconds, although the unconfirmed meitnerium-282 may have a longer half-life of 67 seconds. The GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany, first created this element in … WebThere are four known isotopes of flerovium with mass numbers 286-289. The longest-lived is 289 and it has a half-life of 2.6 seconds. Nuclear theory suggests that isotope 298, with …
