For example, to make flerovium (114 protons, named after Russian physicist Georgy Flerov, who founded JINR), they need to hit plutonium (94 protons) with calcium (20 protons). To make element 118 ...

But we have created much bigger elements than plutonium. The heaviest element ever synthesized is oganesson (chemical symbol Og). It has 118 protons and 176 neutrons, making an atomic mass of 294.

The team of physicists from The University of Arizona say they were motivated by the possibility of Compact Ultradense ...

That's the number of protons in an atom of that element. So they range from one, which is element hydrogen, all the way to element 118 which is the total number of elements in the periodic table ...

Using these machines, the synthesis of superheavy elements then boils down to simple math: to form an element with 116 protons, you need to fuse two atomic nuclei with that sum total of protons ...

The first 117 elements on the periodic table were relatively normal. Then along came element 118. Oganesson, named for Russian physicist Yuri Oganessian (SN: 1/21/17, p. 16), is the heaviest ...

Exploring instability. Atomic nuclei come in a dizzying number of varieties. Scientists have discovered 118 chemical elements, distinguished by the number of protons in their nuclei (SN: 1/19/19 ...
