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.

∙ 9y agoThis is not universal valid. The isotope must be fissile (able to support a fission) and the energy of neutrons is also important. Uranium-238 is fissile with fast neutrons and uranium-235 (also uranium-233) is fissile with thermal neutrons. After the fission the initial nucleus is split.

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
Relative to the mass of the nucleus of the atom the mass of electrons is A. always much smaller B. about the same C. always much larger D. dependent upon the element?
I'd say that the answer is A, always much smaller. The actual mass of an electron in grams is 9.11 x 10-28 grams, while the mass of one proton (or neutron) is about 1.675 x 10-24 grams. Since all the protons and neutrons are located in the nucleus, and the total number of protons and neutrons is about twice the number of electrons, the relative mass of the electrons to the nucleus should always be much smaller.

Which isotope contains the greatest number of protons?
Atomic number is a measure of protons and electrons. extra or less Neutrons are what make an isotope and are not included in atomic number. therefore element with the highest atomic number will also be the isotope with the highest atomic number. on my periodic table it is lawrencium at 103. (note although this might have extra neutrons making it an isotope, it will always have the same atomic number - atomic number isn't what determines an isotope it is mass number) if you meant mass number (which is what determines an isotope), you can subtract the atomic number from the mass number to find out how many neutrons there are and determine whether it is an isotope or not
How many electrons does a neutral isotope of C with 8 neutrons have?
Carbon's atomic number is 6; therefore, any neutral isotope of Carbon will always have exactly 6 electrons: stable neutrons have nothing to do with the electron count of an atom.
What is the neutron and proton responsible for in an atom?
Protons make up the identity of the element and give it its unique properties. Protons have a positive charge. Neutrons give an atom additional mass, and the number of neutrons in an atom make it an isotope of an element. Neutrons have no charge.
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 Pa-231 is hit by a neutron it will always split into the same smaller nuclei?
false
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.
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.
When a unstable isotope decays the daughter isotope that result is always a stable isotope true or false?
false
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!
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.
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.
