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.
Ar-40. Because the atomic mass of argon on the periodic table is 39.948, that is closest to Ar-40, so that isotope must have the highest percentage of all three of the isotopes. List the protons, neutrons and electrons in each isotope, Li-6 and Li-7.
