Tellurium is a non metal element. Atomic Mass of it is 127.
Tellurium is a metal element. Atomic mass of it is 127.
The atomic number of tellurium (Te) is 52.The atomic weight of Te 127.60 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number)
The molar mass of H2Te = 129.61588 g/mol
Tellurium (Te) and iodine (I) would be in reverse order if the elements were placed in order of atomic mass instead of atomic number.

As you move diagonally across the periodic table, from bottom left to top right, the atomic number increases but the average atomic mass decreases. For example, lithium (Li) to helium (He), sodium (Na) to neon (Ne), or potassium (K) to argon (Ar) would exhibit this trend.
Three pairs of elements that are not ordered by atomic mass are: potassium (K, atomic mass ~39.1) and argon (Ar, atomic mass ~39.9), where potassium comes before argon in the periodic table; cobalt (Co, atomic mass ~58.9) and nickel (Ni, atomic mass ~58.7), where cobalt is placed before nickel; and iodine (I, atomic mass ~126.9) and tellurium (Te, atomic mass ~127.6), where iodine precedes tellurium. These examples highlight instances where the arrangement of elements does not strictly follow increasing atomic mass.
The element with 52 atomic mass units (amu) is Tellurium (Te), which has an atomic number of 52.
The element with a mass number of 52 could be tellurium (Te) or antimony (Sb). Both of these elements have isotopes with a mass number of 52.
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.
