Francium is a chemical element with the symbol Fr and atomic number 87. It is extremely radioactive.
Meitnerium is a synthetic chemical element with the symbol Mt and atomic number 109. It is extremely radioactive.
Nihonium is a synthetic chemical element with the symbol Nh and atomic number 113. It is extremely radioactive.
Flerovium is a superheavy artificial chemical element with the symbol Fl and atomic number 114. It is extremely radioactive.
Darmstadtium is a chemical element with the symbol Ds and atomic number 110. It is an extremely radioactive synthetic element.
Polonium is a chemical element with the symbol Po and atomic number 84. It is a rare and highly radioactive metal with no stable isotopes.
Mendelvium is a radioactive metal of the actinide series. It does not occur naturally and was first made in 1955 by bombarding einsteinium with helium ions.
Copernicium is a synthetic chemical element with the symbol Cn and atomic number 112. Its known isotopes are extremely radioactive, and have only been created in a laboratory.
Hassium is a chemical element with the symbol Hs and the atomic number 108. Hassium is highly radioactive; its most stable known isotopes have half-lives of approximately ten seconds.
Roentgenium is a chemical element with the symbol Rg and atomic number 111. It is an extremely radioactive synthetic element that can be created in a laboratory but is not found in nature.
Promethium is a chemical element with the symbol Pm and atomic number 61. All of its isotopes are radioactive; it is extremely rare, with only about 500–600 grams naturally occurring in Earth's crust at any given time.
Livermorium is a synthetic chemical element with the symbol Lv and has an atomic number of 116. It is an extremely radioactive element that has only been created in the laboratory and has not been observed in nature.
Lawrencium is a synthetic chemical element with the symbol Lr (formerly Lw) and atomic number 103. It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements.
Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. This greatly limits the extent of research on dubnium.
Bohrium is a synthetic chemical element with the symbol Bh and atomic number 107. It is named after Danish physicist Niels Bohr. As a synthetic element, it can be created in a laboratory but is not found in nature. All known isotopes of bohrium are extremely radioactive.
Americium is a synthetic radioactive chemical element with the symbol Am and atomic number 95.
Californium is a radioactive chemical element with the symbol Cf and atomic number 98. It is an actinide element.
Neptunium is a chemical element with the symbol Np and atomic number 93. It is a radioactive actinide metal.
Tennessine is a synthetic chemical element with the symbol Ts and atomic number 117. It is the second-heaviest known element.
