What is the product of the alpha decay of U 238?

thorium 234
A nucleus of uranium 238 decays by alpha emission to form a daughter nucleus, thorium 234.

What is an example of alpha decay?

Alpha decay. An example of this decay occurs in the uranium-238 nucleus that decays into thorium-234 nucleus. Alpha particle has a relatively large mass, positive electric charge, and poor radiation penetration, and it can be stopped by a paper sheet (Ilem-Ozdemir and Asikoglu, 2012).

What is the decay series of uranium 238?

For example, the decay chain that begins with Uranium-238 culminates in Lead-206, after forming intermediates such as Uranium-234, Thorium-230, Radium-226, and Radon-222. Also called the “decay series.”.

When U-238 decays by emitting an alpha particle What is the atomic number of the resulting nucleus What is the resulting atomic mass group of answer choices?

Explanation: Uranium-238 produces thorium-234 by alpha decay. An α-particle is a helium nucleus. It contains 2 protons and 2 neutrons, for a mass number of 4.

What is the daughter nuclide when U-238 experiences alpha decay Write your answer as a symbol mass number?

thorium-234
A nucleus of uranium-238 (the parent nuclide) undergoes α decay to form thorium-234 (the daughter nuclide). The alpha particle removes two protons (green) and two neutrons (gray) from the uranium-238 nucleus.

What forms when plutonium 238 undergoes alpha emission?

Uranium-234 is produced as a daughter nuclide when Pu-238 undergoes decomposition.

Which product is formed by alpha emission from uranium 235?

Encyclopædia Britannica, Inc. Decay of uranium-235 into thorium-231 and an alpha particle. Larger, more massive nuclei like uranium-235 become more stable by emitting an alpha particle, which is a helium nucleus composed of two protons and two neutrons. This process is known as alpha decay.

What is an alpha decay explain with an example class 12?

In the α-decay process, the parent nucleus X Z A X 2 Z 2 A X emits an α-particle and produces daughter nucleus Y. The parent nucleus thus loses two protons (charge +2) and two neutrons. The total mass lost is 4 u. The daughter nucleus will, therefore, have mass 4 units less and charge 2 units less than its parent.
