Explanation:
Protons and neutrons make up nearly all the mass of an atom, and each is worth 1 amu. Each atom of an element has a mass measured in amu; thus, its weighted average, or atomic mass, is measured in amu.
Electrons are way way way....lighter so protons and neutrons are taken into account when doing atomic mass.
Osmium is the densest<span> element on earth. It is a hard, weak, pale blue white move metal in the platinum aggregate that is found as a follow component in amalgams, generally in platinum minerals. Osmium is the densest normally happening component, with a thickness of22.59 g/cm3. There is still some open deliberation that Iridium is the denser component as per hypothetical figurings yet starting at now, Osmium has the most noteworthy measured thickness. </span>
