Ununoctium.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Cobalt is an atomic mass of 58.93 atomic mass units
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Ununoctium.
phosphorus
Ununseptium and Ununoctium are currently tied.
Among these three elements, Cl has the greatest mass, as can be seen from any periodic table or other reference work that shows atomic masses.
Not all of the element have been discovered yet , but so far the element with the greatest atomic mass is 112 Uub.
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.
He gave emphasis on the atomic mass. He arranged the elements in the increasing order of their atomic masses
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
