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 is the structure of iodine-131?
Iodine-131 is a radioactive isotope of iodine with 53 protons and 78 neutrons in its nucleus. It decays by beta decay, emitting beta particles and transforming into xenon-131.
What is the number of neutrons in atom I131?
Iodine is element number 53 and and so has 53 protons. There are thus 131-53 = 78 neutrons
If an isotope known as iodine 131 has 53 protons How many neutrons does is have A 78 B 53 C 68 or D 184?
B. 53 neutrons. The number of neutrons in an atom is calculated by subtracting the number of protons from the atomic mass of the isotope. Since Iodine-131 has an atomic mass of approximately 131, and it has 53 protons, the number of neutrons is 131 - 53 = 78.
An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
Which element has 77 protons in its nucleus?
Xenon. Take the atomic mass of 131 and subtract it's protons 54, to get 77 neutrons.
How many neutrons in 134Xe?
is Atomic # 134 then the protons and Electrons would be 134, The Atomic Mass of Xenon s 131. So 134-131= Neutrons 3
What is the mass number for 118 xenon?
Xenon is a non metal element. Mass number of it is 131.
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.
How many protons neutrons does xenon have?
The inert gas xenon (chemical symbol Xe) has an atomic number of 54, and it has 54 protons in its nucleus. The number of neutrons varies, however. Let's look at what's going on. There are 37 different know isotopes of xenon. They range from Xe-110 (with 56 electrons) through Xe-147 (with 93 neutrons). Among these isotopes are the 9 stable isotopes of xenon. They are Xe-124 (70 neutrons), Xe-126 (72 neutrons), Xe-128 (74 neutrons), Xe-129 (75 neutrons), Xe-130 (76 neutrons), Xe-131 (77 neutrons), Xe-132 (78 neutrons), Xe-134 (80 neutrons), and Xe-136 (82 neutrons). Everything other than these is unstable and will have a neutron count that can be found with simple math. Given an isotope, like Xe-147, subtract the number of protons (the atomic number), which is 54, from the isotope number, which is 147 in this case. The 147 - 54 means that there will be 97 protons in the nucleus of a xenon-147 atom. A link can be found below.
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.
An atom with 55 protons and 76 neutrons?
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
