How is it that tellurium has a greater mass number than iodine if an iodine atom has one more proton than a tellurium atom?

Iodine nuclei have one more Proton than Tellurium, but in general the Tellurium atoms have more neutrons, giving a higher average Atomic Mass.
Elements often have isotopes, and their stated atomic masses are averages which look at the abundance of these isotopes.
In a given sample of Iodine, 100% of it will be 127I, though the tiniest trace of 129I will exist. In a sample of Tellurium, 65% will be 128Te and 130Te. This makes Tellurium's average atomic mass a little higher than Iodine's.

Why did mendeleev place tellurium before iodine?
Iodine's atomic number is 53 whereas tellurium's is 52. Atomic number is basically the number of protons that an element has. Therefore, as iodine has more protons than tellurium, it appears later in the table.
Why is the atomic radius of iodine is greater that the atomic radius of fluorine?
Iodine has 53 electrons in its orbitals while fluorine only has nine. This does not even count the proton/neutron variance.
The atomic number of an element determines its?
The atomic number of an element is determined by the number of protons in its nucleus.
Which non-metal element has just one proton?
Hydrogen has only one proton (atomic number 1). It has its nucleus and its single proton.
How do the masses of electrons compare with the masses of protons?
The mass of a proton is 1836 times greater than the mass of an electron.

What has number of proton?
Tellurium ( Te) has an atomic number of 52.
Which of the 117 elements has a proton number of 53?
Iodine has 53 protons.
Why is the atomic radius of iodine is greater that the atomic radius of fluorine?
Iodine has 53 electrons in its orbitals while fluorine only has nine. This does not even count the proton/neutron variance.
Why does iodine have alower average atomic mass that tellurium?
It has a lower atomic number because it has less protons in the nucleus, it has a lower mass number because it has less neutrons and protons in the nucleus. Electrons aren't considered in any of these numbers because they only weigh about 1/2000 of a proton - they are almost weightless, even compared to an atom.
How many neutrons and protons are in te?
Tellurium has an atomic number (proton count) of 52. Stable isotopes include nuclides with 70, 72, 73, and 74 neutrons.
What has a greater electrical force a neutron or proton?
proton
Which subatomic particle has a greater mass a proton or an electron?
Proton has a greater mass than the electron.
Who has more protons iodine or silver?
When looking at the periodic table, we see that Iodine (I) comes after silver (Ag). The clue to this question comes in the atomic number (also known as the proton number), which is the number of protons found in the nucleus of the atom.
Why is mass of neutron and proton greater than mass of electron?
A proton is positively charged and an electron is negatively charged
What is the proton number also called?
The proton number is the atomic number.
An electron has a greater mass than a proton?
the mass of an electron is actually about 1800 times lessthan a proton.
