What is the nuclear equation for thorium?
What is the nuclear equation for thorium?
Thus, uranium-238 decays through α-particle emission to form thorium-234 according to the equation: 238 92 U → l234 90 Th +4 2 He. Note that the sum of the subscripts (atomic numbers or charges) is the same on each side of the equation.
What is the nuclear equation for the alpha decay of thorium 232?
The nucleus that decays is called the “parent” and the one that it tranforms into is called the “daughter.” Here are examples of alpha decay that you will find in your text. 90-Th-232 —> 88-Ra-228 + 2-He-4.
What products are formed when thorium-234 undergoes alpha decay?
A nucleus of uranium 238 decays by alpha emission to form a daughter nucleus, thorium 234. This thorium in turn transforms into protactinium 234, and then undergoes beta-negative decay to produce uranium 234.
What are the products of a nuclear reaction?
A typical nuclear reaction involves two reacting particles—a heavy target nucleus and a light bombarding particle—and produces two new particles—a heavier product nucleus and a lighter ejected particle.
What is the product of the alpha decay of U 238?
thorium-234
Uranium-238 undergoes alpha decay to become thorium-234. (The numbers following the chemical names refer to the number of protons plus neutrons.) In this reaction, uranium-238 loses two protons and two neutrons to become the element thorium-234.
What is the nuclear equation?
Nuclear equations represent the reactants and products in radioactive decay, nuclear fission, or nuclear fusion. Instead of chemical equations where it shows the different number of elements is conserved in a reaction, in a nuclear reaction the atomic mass and proton number are conserved.
What is the nuclear equation for the alpha decay of radon 222?
Radon-222 has an atomic number (Z) of 86 so an atom of radon-222 contains 86 protons in its nucleus. We now have a description of the particle lost as a nucleus that contains 4 nucleons, two of the nucleons are protons….Alpha Decay.

What element would be formed if thorium 230 undergoes alpha decay?
radium-
A. The nuclide thorium-230 undergoes alpha emission to give radium-226 .
What is the decay of thorium-234?
beta particles
When thorium-234 decays, it releases negatively charged radiation called beta particles. A beta particle is an electron emitted by an unstable nucleus. The symbol for a beta particle is 0e.
When U 238 decays to the 234 what has been emitted?
Explanation: A nucleus of uranium-238 decays by alpha emission to form a daughter nucleus, thorium-234. This thorium, in turn, transforms into protactinium-234, and then undergoes beta-negative decay to produce uranium-234.
What is a product nucleus?
The Product Nucleus, on the other hand, gives the engineering team a roadmap of the most important features and functionality to work on first, while not being so specific that time is wasted detailing aspects of the product that will most certainly change, be proven unimportant, or not needed for the first version of …
What is the chemical formula for nuclear fusion?
An important fusion reaction for practical energy generation is that between deuterium and tritium (the D-T fusion reaction). It produces helium (He) and a neutron (n) and is written D + T → He + n. To the left of the arrow (before the reaction) there are two protons and three neutrons.
Is thorium a solid liquid or gas at room temperature?
Thorium Thorium is a chemical element with symbol Th and atomic number 90. Classified as a n actinide, Thorium is a solid at room temperature.
What is the source of thorium in nuclear fuel?
In nuclear fuel, fission gas release is much lower than in UO 2. The most common source of thorium is the rare earth phosphate mineral, monazite, which contains up to about 12% thorium phosphate, but 6-7% on average. Monazite is found in igneous and other rocks but the richest concentrations are in placer deposits,…
What is the atomic number of thorium?
Thorium is a chemical element with symbol Th and atomic number 90. Classified as a n actinide, Thorium is a solid at room temperature. ZSLUVFAKFWKJRC-UHFFFAOYSA-N 232.0377 (4) 232.0377 J.C. Slater, J Chem Phys, 1964, 41 (10), 3199-3205.
Can thorium be used in a thermal neutron reactor?
Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is ‘fertile’ and upon absorbing a neutron will transmute to uranium-233 (U-233) a, which is an excellent fissile fuel material b. In this regard it is similar to uranium-238 (which transmutes to plutonium-239).
