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 protons and neutrons are found in the iodine 129 atom?
The iodine-129 atom has 53 protons and 76 neutrons. This is because the atomic number of iodine is 53 (number of protons) and the atomic mass of iodine-129 is 129 (sum of protons and neutrons).
The number of electrons in an atom of iodine is?
The number of electrons in an atom of iodine is 53.
How many protons and electrons does iodine -131 have?
Iodine-131 has 53 protons and 53 electrons. The number of protons in an atom defines its element, so it remains iodine with 53 protons despite being a radioactive isotope.
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.
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 protons neutrons and electrons does iodine-135 have?
Iodine-135 has 53 protons (same as the atomic number for iodine), 82 neutrons (135 - 53), and 53 electrons (assuming the atom is neutral).
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 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.
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 protons electrons and neutrons does iodine have?
This question is incomplete. One cannot say how many neutrons an atom of iodine has unless one also specifies which isotope of iodine one is referring to. Since the atomic number of iodine is 53, that means that there are 53 electrons and 53 protons in the neutral atom.
How many neutrons does iodine have?
The stable isotope of Iodine is 127 atomic weight and atomic number 53. So it has 53 protons and thus also 53 electrons (to balance the positive charge of the protons) . It has 127-53 = 74 neutrons.
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).
How many protons neutrons and electrons does iodine-122 have?
The isotope iodine-122 has 53 protons and electrons and 69 neutrons.
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.
A certain isotope contains 53 protons 78 neutrons and 54 electrons what is the atomic number?
The atomic number is equal to the number of protons in an atom, which in this case is 53.
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.
