When U-238 decays to th-234 what has been emitted?
An Alpha particle, and associated gamma radiation from the excited nucleus.
What particle is emitted when Pu 240 decays to U 236?
An alpha particle is emitted when Pu-240 decays to U-236. It consists of two protons and two neutrons and is commonly emitted in alpha decay processes.
What particle is emitted when Pu-240 decays to U-236?
240Pu decays to 236U by emitting an alpha particle. You can tell this by looking at the difference in atomic mass. 240 minus 236 is 4, and that is the mass of an alpha particle. You can also tell this by looking at a chart of the nuclides. See the related link below for an example from Brookhaven National Laboratories.

What particle is emitted when Pt-190 decays to Os-186?
An alpha particle is emitted when Pt-190 decays to Os-186. An alpha particle has a mass number of 4, and an atomic number of 2. When Pt-190 decays to Os-186, the mass number drops by 4, showing that an alpha particle is emitted, along with energy. The other form of particle that could be emitted is a beta particle, which has a mass number of 0. The difference between 190 and 186 is 4, thus showing the emission of an alpha particle.

What happens when californium 251 decays into curium 247?
When californium-251 decays into curium-247, it undergoes alpha decay, releasing an alpha particle (helium nucleus) in the process. This results in the transformation of the nucleus to curium-247 with a simultaneous decrease in atomic number and mass number.
When radium-226 decays to form radon-222 the radium nucleus emits a?
When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.
What type of particle is emitted when U-235 decays to Np-235?
It is the reverse: Np-235 decay to U-235 by electron capture.
When thorium decays by emmitting an alpha particle what is the atomic number of the resulting nucleus?
88Ra, Radium
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.
