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 (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 neutrons does iodine cost?
Iodine typically has an atomic number of 53, which means it has 53 protons. The most common isotope of iodine, iodine-127, has 74 neutrons. To find the number of neutrons in an isotope, you subtract the atomic number from the mass number; for iodine-127, that calculation is 127 (mass number) - 53 (atomic number) = 74 neutrons.
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 mass of iodine contains the same number of atoms as 25.0 grams of chlorine?
To find the mass of iodine containing the same number of atoms as 25.0 grams of chlorine, we can first calculate the number of moles of chlorine using its molar mass (Cl: 35.45 g/mol). Next, using the mole ratio of chlorine to iodine (1:1), we can determine the number of moles of iodine. Finally, we can convert the moles of iodine to grams using the molar mass of iodine (I: 126.90 g/mol) to find the mass of iodine.
How many neutrons does iodine cost?
Iodine typically has an atomic number of 53, which means it has 53 protons. The most common isotope of iodine, iodine-127, has 74 neutrons. To find the number of neutrons in an isotope, you subtract the atomic number from the mass number; for iodine-127, that calculation is 127 (mass number) - 53 (atomic number) = 74 neutrons.
How many neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
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.
How many protons neutrons and electrons does ion have?
The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.
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
How neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
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 number of moles in 12.7 grams of iodine?
For this you need the atomic (molecular) mass of I2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. I2=253.8 grams12.7 grams I2 / (253.8 grams) = .0500 moles I2
