Iodine atomic number and atomic mass?

The atomic number of iodine is 53, which means it has 53 protons in its nucleus. The atomic mass of iodine is approximately 126.90 atomic mass units.


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 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.


How do you find out how many neutrons are in iodine?

To find the number of neutrons in iodine, subtract the atomic number (found on the periodic table) from the atomic mass of iodine. Iodine has an atomic number of 53, and the average atomic mass is around 126.9. Therefore, the number of neutrons in iodine is approximately 74 (126.9 - 53).


What is the atomic mass of iodine?

The atomic mass of iodine is 126.90 atomic mass units.


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).


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.


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 element has 127 atomic mass?

Iodine is a non meta element. Atomic mass of it is 127.6.


What is the difference in atomic mass of iodine and magnesium?

The atomic mass of iodine is 126.90 amu, while the atomic mass of magnesium is 24.30 amu. The difference in atomic mass between iodine and magnesium is 102.60 amu.


Atomic number 50 and mass number 125 contains?
