What is the relationship btw atomic mass and atomic mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic no and atomic mass of graphite?
Atomic number 6, atomic mass 12.
Atomic mass and number for carbon?

Hydrogens atomic mass number and relative atomic mass?
Hydrogen is a non metal element. Atomic mass number of it is 12.
Iodine atomic number and atomic mass?
the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127
What is the atomic number and atomic mass of iodine?
The atomic number of iodine is 53, indicating the number of protons in its nucleus. The atomic mass of iodine is approximately 126.9 atomic mass units, which represents the average mass of its isotopes taking into account their abundance.
The atomic mass of iodine is less than the atomic mass?
The atomic mass of iodine is about 126.9 g/mol, which is indeed less than the atomic mass of many other elements. This low atomic mass for iodine is due to its position in the periodic table and the number of protons and neutrons in its nucleus.
What is the atomic mass of iodine?
Atomic mass of Iodine is 126.90447 ± 0.00003 u.
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
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
What is the atomic number for iodine-131?
The atomic number is the same as the number of protons in the nucleus of the particle. Therefore, every atom, ion, and isotope of iodine has an atomic number of 53 (regardless of its mass number).
What is the atomic mass of lodine?
The atomic mass of iodine is approximately 126.9 atomic mass units.
How many neutrons are contained in an iodine nucleus with a mass number of 132 and an atomic number of 53?
79; the mass number is the sum of the protons and neutrons, and the atomic number is the number of protons. So if you take the mass number (protons + neutrons) minus the atomic number (protons), you get the number of neutrons.
What element has 127 atomic mass?
Iodine is a non meta element. Atomic mass of it is 127.6.
How tellurium and iodine show the periodic table is not arranged on basic of increasing atomic mass?
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.
What is the difference in atomic mass of iodine and magnesium?
Iodine is 127 and Magnesium is 24 so the difference is 103 atomic mass units.
