Ununseptium and Ununoctium are currently tied.
Uranium has the heaviest atoms out of these three elements. It is a radioactive element with atomic number 92 and a relatively high atomic mass.
The heaviest man-made element is Oganesson (Og), with an atomic number of 118. It is a synthetic element that was first synthesized in 2002 by Russian and American scientists. Oganesson is highly unstable and has a very short half-life, making it difficult to study.
The atomic mass of francium is approximately 223. It is a highly radioactive element and the heaviest known alkali metal.
Yes, uranium has the heaviest atomic mass between natural elements (238,02891).
The heaviest element with a one letter atomic symbol is uranium (symbol: U).
Uranium - atomic weight; 238,02891 But now it is more correct to consider plutonium as the heaviest natural element (mass: 244 for the isotope 244Pu).
The heaviest element that is highly radioactive is Ununoctium, which has an atomic number of 118.
Francium is the heaviest of the alkali metals, with an atomic mass of 223 grams.
Uranium is the heaviest naturally occurring atom because it has the largest number of protons and neutrons in its nucleus compared to other naturally occurring elements. Its atomic number is 92, with an atomic mass of around 238 atomic mass units.
no its the diamond we did it at school the othere term :P fail
Magnesium is a meta element. Atomic mass of it is 24.
The heaviest element announced in February 2004 was ununpentium with the atomic number 115.
