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.
Yes. Iodine has an atomic number of 53, which means it has 53 protons.
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.
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.
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.
the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127
The atomic number of iodine is 53 which means it has 53 protons.
An atom's atomic number gives its number of protons. Iodine's atomic number is 53. Thus, iodine has 53 protons.
there are 53 protons in the nucleus and 27 electrons on the 2nd shell
Iodine 131, a radioactive and unstable form
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).
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.
Atomic number is equal to the number of protons of an element. Atomic number of sulphur is 16 while the atomic number of Iodine is 53. So iodine has more protons.
Iodine is element number 53 on the periodic table, so it has 53 protons.
It's 53, because the number of protons equal the element's atomic number. You can easily find it on a periodic table.
I-125 contains 73 neutrons. To calculate the number of protons, electrons, and neutrons in an uncharged isotope, follow these rules: Protons = atomic number Electrons = protons = atomic number Neutrons = atomic mass - protons Iodine is number 53 on the periodic table, so its atomic number is 53. It has 53 protons and 53 electrons. This particular isotope of iodine is I-125. So, it has 125-53=72 neutrons.
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.
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.
