The atomic number of tellurium (Te) is 52.
The atomic weight of Te 127.60 grams per mole.

I want to know what the atomic mass of tellurium is......... It has not answered my question and I would like to know the answer....
Tellurium is a non metal element. Atomic mass of it is 127.
Tellurium is a metal element. Atomic mass of it is 127.
They show that the periodic table isn't arranged on the basis of increasing atomic mass because iodine has a mass lesser than tellurium. Iodine has a mass of 126.90 and tellurium has a mass of 127.60.
Iodine is a non meta element. Atomic mass of it is 127.6.

Tellurium.
Tellurium is a metal element. Atomic mass of it is 128.
the 127.6 stands for the relative atomic mass, which is the number of protons and neutrons in tellurium. the number down the bottom indicates the atomic number which for tellurium is 52 so that means there are 52 protons and 127.6 subtract 52 = 75.6 so there are 75.6 neutrons :)
Iodine has a higher atomic number (53) because it has one more proton in its nucleus than tellurium (52). However, iodine's lower atomic mass compared to tellurium is due to differences in their isotopic composition. Isotopes of iodine with lower mass numbers are more abundant, leading to a lower average atomic mass for iodine compared to tellurium.
The atomic mass of an element is determined by the total number of protons and neutrons in its nucleus. Iodine (atomic number 53) has more protons than tellurium (atomic number 52), but its atomic mass is lower because it has fewer neutrons. While iodine has 53 protons, it typically has 74 neutrons, giving it an atomic mass of about 127 amu, whereas tellurium has 52 protons and usually 76 neutrons, resulting in an atomic mass of about 128 amu. The different neutron counts in their isotopes lead to iodine having a lower atomic mass despite having more protons.
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 Atomic Mass usually increases, but there are a few exceptions, such as tellurium to iodine.
