There is no element with that high a mass. Although, I believe you forgot the ., which should be "35.453" that is Cl.

What is the atomic number and atomic mass of iodine?
The atomic number of iodine (I) is 53.The atomic weight of I is 126.90 grams per mole.Iodine is a diatomic molecule, I2.See the Web Links to the left of this answer for a periodic table with more information about this element!
How many nucleons are in the atom of iodine-131?
The 131 number is the mass number: the sum of the number of protons and neutrons. Iodine has 53 protons and will have 53 electrons if its a neutral atom. To find the number of neutrons, just subtract the mass number with the number of protons 131 - 53 = 78 neutrons. See link below for periodic table.
What element has 53 as its atomic number?
Iodine.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
What is the mass of an element?
The mass number of an element is the atomic mass rounded to the nearest whole number. For Example, if the atomic mass is 54.94 (Manganese [Mn]), then the mass number will be 55. You can use the mass number to calculate the amount of neutrons in an isotope.

What element number does iodine have?
it has 53 number
What is the atomic mass of and atom?
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) or to the average number allowing for the relative abundances of different isotopes.

To find the number of neutrons, just subtract the mass number with the number of protons 131 - 53 = 78 neutrons. See link below for periodic table.
How do you find out how many neutrons are in iodine?
To find out how many neutrons are in any element, you must take the atomic mass of the element and subtract the atomic number/ the number of protons. # of neutrons = atomic mass - # of protons This is because the atomic mass of an element is the number of protons added to the number of neutrons. The atomic mass is measured in atomic mass units, where one proton has a mass of 1 amu and one neutron has a mass of 1 amu. Elements also have electrons, however their mass is negligible, which means that it can be ignored because it is minor. In the case of iodine, it's atomic mass is approximately 127 (126.9). It's atomic number, which is also the number of protons and the number of electrons, is 53. Thus, the number of neutrons is: 127 - 53 = 74
