Since an alpha particle is simply two protons and two neutrons bound together, or He2+, the alpha decay of selenium-78 is easily determined. Selenium-78 has 34 protons and 44 neutrons. Subtract 2 from each of these due to the loss of the alpha particle and you have 32 protons and 42 neutrons. This new atom is germanium-74.
What else can I help you with?
The least energetic of the forms of radioactive decay is ______?
alpha decay
Which two elements undergo alpha decay?
The two elements that undergo alpha decay are uranium and thorium.
What is the nuclear equation for the alpha decay of 242 Pu?
The nuclear equation for the alpha decay of 242Pu is: ^24294Pu -> ^23892U + ^4He2 This equation shows that the nucleus of 242Pu decays into a nucleus of 238U and an alpha particle, which is a helium-4 nucleus.
What type of decay does Am-241 undergo to become Np-237?
Americium-241 undergoes alpha decay to become Neptunium-237. During alpha decay, an alpha particle (two protons and two neutrons) is emitted, resulting in the conversion of Americium-241 to Neptunium-237.
When bismuth-212 undergoes alpha decay, what does it become?
When bismuth-212 undergoes alpha decay, it becomes thallium-208.
Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
Order gamma decay beta decay and alpha deacy form weakest to strongest?
From weakest to strongest decay, the order is: Gamma decay - involves the emission of high-energy photons. Beta decay - involves the emission of beta particles (electrons or positrons). Alpha decay - involves the emission of alpha particles (helium nuclei).
What is the type of radioactive decay in which positive particles are given off?
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
What type of decay is 235 92U---4 2 He plus 231 90Th?
The type of decay for this process is alpha decay. In alpha decay, a heavy nucleus emits an alpha particle (helium-4 nucleus) to transform into a new element with a lower atomic number.
Alpha and beta decay emit what?
Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).
What is the heaviest of the forms of radioactive decay is?
I'm pretty sure its alpha.
What is the charge of the emitted particle in alpha decay?
In alpha decay, the emitted particle has a charge of 2.
What is the nuclear equation for the decay of radium 226?
The equation for the alpha decay of 226Ra: 88226Ra --> 86222Rn + 24He The alpha particle is represented as a helium (He) nucleus.
What are the possible products of the alpha decay of uranium-238?
The possible products of the alpha decay of uranium-238 are thorium-234 and helium-4. During alpha decay, the uranium nucleus releases an alpha particle (helium nucleus) and transforms into thorium-234.
What is the nuclear equation for the alpha decay of uranium 239?
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
The least energetic of the forms of radioactive decay is ______?
alpha decay
What type of decay is involved when polonium -214 decays into lead -210?
Alpha decay is involved when polonium-214 decays into lead-210. In alpha decay, an alpha particle (2 protons and 2 neutrons) is emitted from the nucleus, reducing the atomic number by 2 and the mass number by 4.
