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).

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 ...

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.

One of the most abundant elements on our planet and in the human body is oxygen, in particular the isotope oxygen-16. With ...

While calcium 48 and the heavier berkelium (97 protons) have been used to synthesize element 117, berkelium “is extremely difficult to produce,” says Witold Nazarewicz, chief scientist at the ...

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 ...
