Heavier elements have more protons, ... Based on our calculations, we expect stable metals with atomic numbers around 164 to have densities between 36 to 68 g/cm3 (21 to 39 oz/in3).

It "would have a density between 36.0 and 68.4 g/cm 3: ... it would mean CUDOs like asteroid Polyhymnia could be made of material that contains elements with as many as 164 protons per atomic nucleus.

Discover the history, structure, and importance of the periodic table of elements, from Mendeleev’s discovery to modern scientific applications. When you purchase through links on our site, we ...

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 ...

Physics Protons seem to be a different size depending on how you look at them. An experiment that probed particles called gluons, which contain most of the mass of a proton, has revealed that a ...
