The non-synthetic element that has the largest atomic mass is uranium, although it is radioactive. The atomic mass of uranium is 238.0289.
No, the element with the largest atomic mass is not always present in the highest percentage by mass in a compound. The percentage by mass of an element in a compound is determined by its atomic mass and the total mass of the compound. The composition of a compound can vary based on the number of atoms of each element present.
Radon, unless you count the synthetic Ununoctium. But because it is radioactive, highly unstable, and synthetic, I would discount it for now. It does however have the largest atomic mass for any known atomic substance. So, the answer is Radon.
Atomic mass
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
The relative atomic mass of ununoctium is estimated as 294.
Element hassium has the largest Atomic Mass.
Yttrium is the largest metal in group three. It is atomic number 39 and has an atomic mass of about 88.9.

Sometimes, but not necessarily: The largest percent by mass in a compound is that of the element for which the product of the subscript and the atomic weight is highest. For example, there is more carbon than hydrogen by mass in CH4.

Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The largest element among boron, carbon, oxygen, and nitrogen is oxygen. It has the highest atomic number and atomic mass compared to the other elements listed.
