Alpha decay is basically a helium atom, so 235-4= 231. And 92-2=90 (Uranium's atomic number minus helium's). The element with atomic number 90 is Thorium. The mass is 231, so you should have Th-231 (Thorium-231).

What product is produced when 232 90 Th undergoes alpha decay?

90Th232 undergoes alpha decay to form 88Ra228. Remember, in alpha decay, a helium nuclei is emitted, comprising two protons and two neutrons. As a result, the atomic number goes down by 2, and the atomic mass number goes down by 4.


Alpha decay and beta decay are two forms of decay that cause transmutation?

Transmutation, which is the change of atoms from one element to another.


How do the three forms of radioactivity change the atomic number?

They don't. Only atoms really have an atomic number, which is the number of protons in each atom, so when that number changes as in alpha and beta radiation the atom no longer has a neutral charge and becomes an ion. Gamma radiation is an electro-magnetic wave so it doesn't affect the atomic number and the particle is still an atom. Hypothetically, nd I'm not sure it's possible, alpha radiation would reduce the atomic number by 2, beta would reduce it by 1 and gamma doesn't reduce it at all anyway.


Do alpha particles consist of two protons and two neutrons?

No. A beta particle is either an electron (beta-) or a positron (beta+). An alpha particle consists of 2 protons and 2 nuetrons bound together. It's actually a helium-4 nucleus that has been emitted as a result of nuclear decay. Both types of beta particle and the alpha particle are forms of particulate radiation that result from nuclear decay of radioactive materials. Which form of decay and the energies of the particles as they leave the nucleus vary as the radionuclide emitting them.


Are alpha beta or gamma emitted by the sun?

Yes, all three forms of radiation are present in the sun. Alpha particles are simply helium atoms, and helium is being formed constantly by the fusion of hydrogen, although this is not considered alpha radiation as it is not involving radioactive decay. Beta radiation is high energy electrons, which are likely to be present in the sun. And finally, gamma rays are emitted during the process of fusion. However, the vast majority are absorbed within the Sun's core and therefore do no radiate from the Sun.
