Thorium nucleus has 90 protons and electrons and 142 neutrons.
No, it is not true !
In beta decay of thorium-234, a neutron in the nucleus of thorium-234 is transformed into a proton, releasing an electron (beta particle) and an antineutrino. This process converts the thorium-234 nucleus into protactinium-234.
This decay occurs due to the instability of the uranium-238 nucleus, which undergoes alpha decay to achieve a more stable configuration as thorium-234. During alpha decay, a helium nucleus (two protons and two neutrons) is emitted from the uranium-238 nucleus, leading to the transformation into thorium-234.
The mass defect of thorium refers to the difference between the mass of the individual protons and neutrons in its nucleus and the actual mass of the thorium atom. This mass defect arises because some mass is converted into binding energy that holds the nucleus together, as described by Einstein's equation, E=mc². For thorium-232, which is the most common isotope, the mass defect is approximately 0.180 atomic mass units (u). This binding energy is crucial for the stability of the nucleus.

The balanced equation for the alpha decay of thorium-229, Th-229, is: Th-229 -> Ra-225 + He-4 This equation shows that a thorium-229 nucleus undergoes alpha decay to form a radium-225 nucleus and a helium-4 particle.
Uranium-235 decays primarily through alpha decay, where it emits an alpha particle (helium nucleus) and transforms into thorium-231.
The beta decay is: 234Th--------beta--------234Pa.
Common compounds of thorium: thorium dioxide, thorium trifluoride, thorium tetrafluoride, thorium tetrachloride, thorium triiodide, thorium diiodide, thorium tetraiodide, thorium nitrate, thorium oxalate, thorium carbide, thorium sulfides, thorium nitride, thorium oxinate, etc.
No, thorium emitting a beta particle is a nuclear reaction, not a chemical reaction. In a beta decay process, a neutron in the thorium nucleus converts into a proton, emitting a beta particle (an electron) and an antineutrino. This type of decay is a form of radioactive decay, which is a nuclear process involving changes in the nucleus of an atom.
The resulting element is protactinium, atomic number 91.
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.
