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 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 true of iodine and radioactive iodine a-Both have the same atomic number b-Both have the same number of electrons c-Both have the same number of neutrons d-None of the ab?
both a and b are true for iodine and radioactive iodine isotope
What is the mass of one mole of Iodine?
The number 115 is the mass number, so the mass is 115 amu. One amu (atomic mass unit) is about 1.66 x 10-27 kg, so if your looking for the mass of one atom of In-115, multiply 1.66 x 10-27 kg by 115. That's about 1.9 x 10-25 kg. You chemistry teacher should have taught you this, and probably did, if you were paying attention in class.
What is the symbol for iodine?
Iodine has the symbol I and atomic number 53.
How many protons and neutrons are found in the iodine 129 atom?
It's 53, because the number of protons equal the element's atomic number. You can easily find it on a periodic table.
How many neutrons are in most atomic of iodine if the atomic number is 53 and the atomic weight is 126.9?
Most atomic of iodine has 74 neutrons. The atomic weight of iodine (126.9) represents the combined mass of protons, neutrons, and electrons in the atom. Since the atomic number (53) represents the number of protons in the nucleus, subtracting the atomic number from the atomic weight gives the number of neutrons.
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.
How many neutrons are in iodine-127.?
Refer to the Periodic Table. Iodine has atomic Number of 53. This tells us that there are 53 protons in the nucleus. I-127 is the Atomic Mass. The figure is the total of all the protons and neutrons in the nucleus of the atom. So the total number of neutrons will be 127 - 53 = 74 neutrons.
How many protons are in the nucleus of Iodine-131?
The atomic number of iodine is 53 so there are 53 protons in the nucleus, irrespective of which isotope you are considering. 53 is the atomic number and defines iodine.
How many protons electrons and neutrons respectively does iodine 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.
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 protrons and neutrons are in iodine?
you can find the number of protons by looking at the atomic number (53), as the number of protons does not change between isotopes. You can find the number of neutrons by subtracting the atomic number from the Atomic Mass (131), therefore, iodine-131 has 53 protons and 78 neutrons.
How many neutrons and protrons are in iodine-131?
you can find the number of protons by looking at the atomic number (53), as the number of protons does not change between isotopes. You can find the number of neutrons by subtracting the atomic number from the atomic mass (131), therefore, iodine-131 has 53 protons and 78 neutrons.
What is the Atomic weight of iodine-126?
126 atomic mass units. 53 protons 73 neutrons
How many number of protons is in the nucleus of iodine?
An atom of iodine contains 53 protons in its nucleus. This number can be obtained by looking up iodine's atomic number on the periodic table. Atoms' atomic numbers are equal to the number of protons they contain.
A certain isotope contains 53 protons 78 neutrons and 54 electrons what is the atomic number?
Iodine 131, a radioactive and unstable form
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.
