1. 1  the âIâ or self of any person; a person as thinking, feeling, and willing, and distinguishing itself from the selves of others and from objects of its thought.
The largest atomic mass for an artificial element (or any element) would be Ununoctium. Neutronâ¦ stars, which are neutrons densely packed together surrounded by a thin layer of degenerate matter could possibly be considered atomic nuclei, though their specific proton count would probably not be measurable.
Hydrogen, the lightest element, has one proton in its nucleus, and uranium, the heaviest naturally occurring element, has 92. Element 118 would fit comfortably just below radon in a column of the periodic table containing what are called noble gases for their inert chemical properties.n element s weight is determined by the total number of protons, which have a positive electrical charge, and neutrons, which are neutral, in its nucleus. By that measure, too, the new element is the heaviest ever created.
