When U-238 decays to th-234 what has been emitted?
When U-238 decays to Th-234, an alpha particle is emitted. An alpha particle consists of two protons and two neutrons, and is essentially a helium nucleus.
When radium-226 (atomic number 88) decays by emitting an alpha particle it becomes .?

What alpha decays to 234Th and α?
Th-230 -> He-4 + Ra-226 Thorium which alpha decays produces an alpha particle (Helium 4) and a Radium-226 atom.

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.

When U-238 decays to Th-234, an alpha particle is emitted. An alpha particle consists of two protons and two neutrons, and is essentially a helium nucleus.
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.

How many protons and neutrons are lost as U234 decays to Th230?
2 of each in the form of an alpha particle.
What type of decay is involved when polonium -214 decays into lead -210?
It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
Are the alpha particle and helium nucleus the same thing?
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
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.
