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!
53 protons what will be the atomic number?
The atomic number of an element is defined by the number of protons it has. Therefore, if an atom has 53 protons, its atomic number is 53. This corresponds to the element iodine (I) on the periodic table.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
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.

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
What element number does iodine have?
it has 53 number
What chemical has 53 neutrons and 42 electrons?
42 electrons implies atomic number of 42, which implies that it's molybdenum. With 42 electrons implies 42 protons implies an atomic mass of 42+53=95 which is 95Mo, one of the stable isotopes of this element. Please see the link.
53 protons what will be the atomic number?
The atomic number of an element is defined by the number of protons it has. Therefore, if an atom has 53 protons, its atomic number is 53. This corresponds to the element iodine (I) on the periodic table.
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.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
Who is atomic number is 53?
Iodine is a none metal element. atomic number of it is 53.
What protons does iodine have in the periodic table?
Iodine is element number 53 on the periodic table, so it has 53 protons.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
A certain isotope contains 53 protons 78 neutrons and 54 electrons what is the atomic number?
Iodine 131, a radioactive and unstable form
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.
