What else can I help you with?
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.
An isotope of nitrogen could have more protons neutron electrons?
An isotope of nitrogen will always have 7 protons, as this defines the element. However, it can have a different number of neutrons, thus changing the mass number of the isotope. The number of electrons in an isotope is equal to the number of protons to maintain overall charge neutrality.
What element is composed of one proton and one neutron?
Hydrogen [H] has one proton. Its atomic number is 1 which is the number of protons. Also, the number of protons will always equal the number of electrons unless the element has a charge.
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
When a certain isotope such as Pa-231 is hit by a neutron it will always split into the same smaller nuclei?
false
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.
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.
An isotope of nitrogen could have more protons neutron electrons?
An isotope of nitrogen will always have 7 protons, as this defines the element. However, it can have a different number of neutrons, thus changing the mass number of the isotope. The number of electrons in an isotope is equal to the number of protons to maintain overall charge neutrality.
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.
Is a radioactive atom always an isotope?
No, not always.
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.
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!
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.
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.
What element is composed of one proton and one neutron?
Hydrogen [H] has one proton. Its atomic number is 1 which is the number of protons. Also, the number of protons will always equal the number of electrons unless the element has a charge.
