What happens if an atom of uranium loses a proton?
If an atom of uranium loses a proton, it becomes an atom of an element with one less proton in its nucleus, known as an isotope of a different element. This change can alter the atomic number, mass number, and chemical properties of the atom.
How are uranium and plutonium alike?
Plutonium has the same composition as uranium, except for the fact that it contains one more neutron and one more proton. Actually Plutonium-239 has 2 more protons and 2 more neutrons than Uranium-235.
Is Thorium-234 Proactinium-234 -1 a alpha decay equation?
It's beta decay. Actually, it's beta minus decay. A neutron in the nucleus of thorium-234 undergoes beta minus decay and changes into a proton with the subsequent release of an electron, an antineutrino and some energy. The transformation of a neutron in the thorium nucleus into that proton creates another element. You'll recall that the identity of an element is determined solely by the number of protons in its nucleus. And our thorium atom has now become a protractinium-234 atom. Links are provided below for more information.
What two elements would result from the alpha decay of plutonium 238?
First off, it's better to be more careful in regards to the word element. What you actually mean is isotope. The difference is subtle, but important. If I had a large rock of Uranium ore that was just mined, you could say I had the element Uranium. However, the element is made up of a certain percentage of isotopes, those being a nucleus that has the same number of protons, 92 in this case, but different numbers of neutrons.Secondly, alpha decay is defined as the spontaneous emission of a helium 4 nucleus from an isotope, so one of your two resulting elements when alpha decay is involved is always going to be helium. The other element is found by simply subtracting 2 from Pu's atomic number, which is 94, giving you the resulting element's atomic number, which is 92, otherwise known as uranium, specifically, the isotope U 234.
Ion of sodium isotope of uranium proton of hydrogen or proton of oxygen is most likely to be radioactive?
Hydrogen has only one natural radioactive isotope(3H), of cosmogenic origin, but only in ultratraces on the earth. Sodium has two radioactive natural isotopes (22Na and 24Na), of cosmogenic origin, but only in ultratraces on the earth. Oxygen has not natural radioactive isotopes. All the isotopes of uranium are radioactive.
How many electrons in 234U?
92. All isotopes of Uranium have 92 protons. The number of protons in each element is represented by the atomic number of that element. Uranium is atomic # 92, so it will always have 92 protons. The difference in atomic mass (that's the 234 here) is due to difference in number of neutrons. Atomic mass is calculated (#of protons + # of neutrons), so Uranium-234 has 92 protons and 142 neutrons. Uranium-235 would have 92 protons and 143 neutrons and so forth. The number of protons contained in the nucleus of ANY atom will remain constant in ALL isotopes of the same element. Ex. Carbon-12 has 6 protons and 6 neutrons, Carbon-13 has 6 protons and 7 neutrons, etc. Carbon has an atomic number of 6. If the number of protons in the nucleus of an atom were different, it would no longer be the same element. Ex. Carbon - atomic #6 - has 6 protons with one more proton in the nucleus, it would have 7, and have atomic # 7.... then it would just be...... Nitrogen! Nitrogen - atomic #7 - has 7 protons
How many electrons does it take to equal to the mass of one proton?
electrons are a 2000th of the mass of a proton/neutron. Because of this very low mass, electrons dont affect the mass number of elements on the periodic table
How many years will it take for 10 g of radioactive uranium to decay into 5 g of radioactive uranium?
It would take one half-life for the 10 g of uranium to decay into 5 g. The half-life of uranium is around 4.5 billion years, so it would take approximately 4.5 billion years.
How may electrons equal one proton?
In charge, spin, and strangeness; they are exactly equal. In mass, it would take about 1836 electrons to equal a proton.
What is the U-235 content of depleted uranium (DU)?
Depleted uranium is uranium with a content of the isotope uranium-235 under 0.7 %. Natural uranium has been processed to change (increase) the concentrations of lighter isotopes, and the "leftovers" are termed depleted uranium. Let's look at this heavy metal and sort things out. Without splitting hairs, the element uranium as it comes out of the ground is almost 99.27% U-238, and about 0.73% U-235. There's also a trace of U-234 in it. The isotope U-235 is the desired one for use in nuclear fuels and in nuclear weapons. Uranium is processed or "enriched" to increase the amount of the lighter isotope in the the finished product. This leaves the rest of the uranium "depleted" of some (or much) of its U-235 (and U-234, for what it's worth). The term depleted uranium is then applied to the remaining uranium. A link can be found below to check facts and gather more information.
Does uranium decay to lead in one step?
No, it's a long chain. The decay sequence is: Uranium-238 to thorium-234 to protactinium-234 to Uranium-234 to thorium-230 to radium-226 to radon-222 to polonium-218 to lead-214 to bismuth-214 to polonium-214 to lead-210 to bismuth-210 to polonium-210 to lead-206 which is its final stable form. Radioactive decay occurs when an unstable (radioactive) isotope transforms to a more stable isotope, generally by emitting a subatomic particle such as an alpha or beta particle (helium nucleus or electron). The half-life of one of the elements above can be shorter than a millisecond (Po-214) or as long as 4.5 billion years (U-238).
When was Uranium One created?
Uranium One was created in 1997.
