Cesium has an atomic number of 55. Fifty-five indicates the number of protons and electrons. The task here is to find the number of neutrons. To do so, take 134 and subtract 55 to get 79.

∙ 14y agoCesium has an atomic number of 55, so the number of neutrons equals the Atomic Mass minus this. Therefore, Cs-137 has 82 neutrons and Cs-134 has 79 neutrons.

∙ 6y agoCs has 55 protons, so the number of neutrons in Cs-134 will be 134 - 55 = 79 neutrons.

∙ 9y agoi think it is 137-55= 82, yes it is,

How many atoms are in barium?
Barium, or Ba, has an atomic number of 56, which means it has 56 protons and 56 electrons (if it is neutral). Its atomic weight is 137.33, which means it has a total of 137.33 neutrons AND protons put together. It has 81 neutrons (137 minus 56).

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
How many protons neutrons and electrons are in radium 222?
Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
How many neutrons are there in isotope Rn 220?
The atomic number is 86 which gives the number of protons. 220Rn has 220 protons and neutrons so the neutron count iscalcualted as follows: 220 -86 = 134 neutrons 220Rn is an unstable isotope of Radon.
What is the element 54 protons 54 neutrons and 78 electrons?
I think you meant "54 protons, 54 electrons, and 78 neutrons," because I don't think it's possible for any element to have such a high proton-electron different, especially when that element is the noble gas Xenon. Anyways, if you did make a typo, the element you're thinking of should be Xenon-134
How many neutrons does platinium have?
Platinum has 6 naturally occurring isotopes, all of which have 78 protons. The number of neutrons can vary, but the most common isotopes have between 116 and 118 neutrons. The full list of isotopes is:190Pt (78 protons and 112 neutrons)192Pt (78 protons and 114 neutrons)194Pt (78 protons and 116 neutrons) about 1/3 of all platinum195Pt (78 protons and 117 neutrons) about 1/3 of all platinum196Pt (78 protons and 118 neutrons) about 1/4 of all platinum198Pt (78 protons and 120 neutrons) about 1/14 of all platinum
How is the structure of the nucleus of a polonium 218 atom different from the structure of the nucleus of a radon 222 atom?
Polonium-218 has 84 protons, 84 electrons and 134 neutrons.Radon-222 has 86 protons, 86 electrons and 136 neutrons.
What is the mass number for cesium?
The standard atomic weight for cesium is 133. There are 3 other radioactive cesium isotopes that have atomic weights of 134, 135, and 137. Cesium 133 is the only one that is found in nature. The other isotopes are synthetic.
How many neutrons does U-235 have?
Uranium 235 has 92 protons and 92 electrons. To find the number of neutrons, follow this equation: Mass # - Atomic # = # of neutrons. Since the mass number of uranium 235 is 235 and has an atomic number of 92, the number of neutrons is 143.

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.

When a parent radioactive nucleus splits by ejecting an alpha particle the remaining nucleus has what left?
two protons and two neutrons less than the original nucleus.* A lower atomic mass (-4)* A lower atomic number (-2)In alpha decay, an alpha particle (helium nucleus) is given off.An alpha particle consists of 2 protons and 2 neutrons. THus the atom loses 2 protons and 2 neutrons. Proton number endows the identity of the element. The daughter nucleus is thus of a different element to the parent nucleus. It also has 2 fewer protons. Radium can decay by alpha emission, losing 2 protons from the original 88, leaving a nucleus of Radon with 86 protons.Neutrons and protons summed give the mass number of the atom. SInce an alpha-decayed nucleus loses a sum of 4 particles (protons and neutrons) the mass number goes down by 4.NovaNET answer: 2 protons and 2 neutrons less
