∙ 10y ago1. The nuclear reaction for neutrons absorption (n,gamma) is:
U-238 + n------U-239-------Np-239--------Pu-239
2. The fission products of a nuclear fission are not individually predictable; this is possible only statistically.

What is the protons neutrons and electrons of helium?
The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.
Do the heaviest objects always have the largest volumes?
Nop. The mass and the volume are related by the density of the object across: density = mass / volume So, given the mass, the volume is strictly determined by the density. For example, iron is much denser than wheat. 1 kg of iron has a volume, then, smaller than 1 kg of wheat. In fact, the heavier the object, usually the smaller the volume. This is a consequence of gravitation force. The heaviest objects in the Universe (neutron stars, black holes...) are, in spite of their mass, very very small in volume. One tea spoon of a neutron star has a weight of, more or less, 1 billion of kg.
How many neutrons does nobelium have?
157; you figure that out by taking the atomic mass (259) and subtract it by the # of protons (102) and the answer is the # of neutrons. ( the atomic #, # of protons, and # of electrons are always the same # 102 ). But each isotope of nobelium has a different number of neutrons, depending on the atomic mass.
What is the charge of an atom if the number of protons is more than the number of neutrons What kind of particle is this called?
To answer the second part of your question, an element with varying neutrons is an isotope, and to determine which isotope it is we have the chemical symbol plus the mass number (ie C-14). Going back to the first part, this question is a bit flawed. Protons are relative to the element itself. The atomic number is equal to the number of protons. So nitrogen will always have 7 protons. Neutrons have no charge (neutron=neutral), so a varying amount of neutrons will not affect the charge. To alter your charge you need to look into the amounts of electrons as relative to the amounts of protons, but that's a different matter.
What type of lens always produces smaller images?
Concave D. Diverging
When a certain isotope such as Pu 239 is hit by a neutron it will always split into the same smaller nuclei true or false?
false
Is the parent isotope always radioactive In a nuclear equation?
No, the parent in the nuclear equation is not always radioactive. For example, the following reaction shows a neutron capture by 23Na, which is not radioactive. 1123Na + 01n --> 1124Na where 01n is a neutron.
When a certain isotope such as U 238 is hit by a neutron it will always split into the same smaller nuclei?
No, not at all. Simple decay (alpha decay, beta decay, K capture, etc.) will always produce the same daughter products, but with neutron-induced fission it's ... well, it's not quiterandom, but it's certainly not going to always produce the same products.
What element has the neutron number of 30.69?
This is the weighted average neutron number for the naturally occurring isotopes of nickel, which has the atomic number 28 and the gram-atomic mass of 58.69. In an individual isotope, the neutron number is always the isotopic atomic mass number minus the atomic number, and the same principle applies to the weighted average neutron number for the naturally occurring isotopes of an element.
What is a name of an atom that has a positive or negative neutron?
There is no such thing as a "positive neutron" or a "negative neutron". A neutron is always neutral.
Is a radioactive atom always an isotope?
No, not always.
When a unstable isotope decays the daughter isotope that result is always a stable isotope true or false?
false
What do you call a heavier version of an atom of the same element?
You call it an isotope. And it isn't always heavier; it can be lighter, too. An isotope is an atom of a certain element with a different number of neutrons. It usually has a lot of the same physical and chemical properties of the parent element, but it will have a different atomic mass because of the different neutron count. Many isotopes are radioactive, and therefore unstable, since they undergo decay over a certain period of time. Isotopes make possible radiocarbon dating and smoke detectors, so they're quite useful.
How do you find the atomic number of an isotope?
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.
What are the atomic number for the hydrogen isotope with 1 neutron?
Atomic number of hydrogen is (always) 1. The mass number is 2, sum of number of protons (1 in H) and neutrons (1 in H in this case). This isotope of hydrogen is called deuterium.By the way: neurons (without t) is a very different thing!
Will each atom of an element always have the same number of neutrons?
No many elements have multiple isotopes with different numbers of neutrons. Every atom of a certain isotope has the same number of neutrons
How many electrons does an isotope of nitrogen-15 always have?
Seven.
