Seems some mistake in printing the mass number of thorium. It has to be 227.
No Th-225 is available as far as the tables have been analysed.
When a alpha particle comes out then the atomic number of parent is reduced by 2 and its mass number will be reduced by 4. So in case of Th-227, it gets changed to Ra-223 after the emission of an alpha particle.

What is a balanced equation for the alpha decay of thorium -232?
Alright so you begin with what you need, this isotope of Protactinium has 234 nucleons, its atomic number is 91, in Beta decay we release an electron, which has no nucleons (protons and neutrons) and an atomic number of -1 so when we take out -1 from 91, so 91 - -1 we get 92, which is of course Uranium, this particular isotope has 234 nucleons, now, to show where it has gone, write the electron in, and add a antineutrino aswell, heres how mine looks. Pa23491 ---> U23491 + e0-1 + antineutrino (a v with a little line above it) Hope this helps :)
Would you use uranium 235 or thorium 232 to date a sample that was about million years old?
Uranium dating is recommended. Thorium dating (but with the isotope 230Th, not with the isotope 232Th) is recommended to minerals old of up to 500 000 years.
How radioactivity of thorium important?
Some thorium uses: - fertile material (as ThO2) in nuclear power reactors; is a precursor of the fissile isotope 233U. - thorium dioxide can be used as refractory material for crucibles, tubes, rods, etc. - thorium tetrafluoride (ThF4) is used as anti-reflection coating in optics. - gas mantles (as ThO2) - alloying metal for some aviation components (magnesium-thorium alloy, magnesium-zinc-thorium); also for welding alloys wolfram-thorium - additive (as ThO2) in wolfram filaments - to stop crystalline growth of W and to increase time of use of light bulbs - catalyst in organic chemistry (as ThO2) - additive for special glass (as ThO2) - additive in filaments (as ThO2) of magnetron tubes - reagent in chemistry laboratories (as thorium nitrate) - etc.
Can you Draw a Bohr model of thorium?
See an example at: http://education.jlab.org/qa/atom_model.html and note that thorium 232 has 90 protons, 142 neutrons and also 90 electrons; the electron configuration is [Rn] 6d27s2.
Is there nuclear power in earth's core?
Whar exactly is in the earth's core is not known, but it is surmised to be solid iron and perhaps other metals, at very high pressure and temperature. The heat contained here is possibly what is left over from when the earth was formed. In addition it is thought that some of the earth's heat continues to be produced by the radioactive decay of potassium-40, uranium-238 and thorium-232 isotopes. All three have half-life decay periods of more than a billion years. At the center of the planet, the temperature may be up to 7,000 K and the pressure could reach 360 GPa. A portion of the core's thermal energy is transported toward the crust by Mantle plumes; a form of convection consisting of upwellings of higher-temperature rock.
What isotopes remains after the alpha decay of uranium-238?
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
How far can alpha particles from Thorium-232 decay travel in body fluids?
Alpha particles with energies of 4.0 MeV from Thorium-232 decay can travel less than 28 microns in body fluids.
What type of radiation alpha beta or gamma is emitted by thorium-230?
alpha particles.
What type of radiation is emitted by thorium?
Thorium-232 is an alpha emitter; rarely decay by spontaneous fission or double beta decay are possible.
How far can alpha particles from Thorium-232 travel in body fluids?
An alpha particle with energy of 4.0 MeV from Thorium-232 decay can travel less than 28 microns in body fluids.
This equation is an example of what nuclear decay 232 90 Th to 4 2 He plus 228 88 Ra?
Alpha
How many types of radiation does thorium give off?
The isotope thorium-232 is an alpha emitter; extremely rare are decays by spontaneous fission or double beta emission.
Why branching decay occur in thorium series?
Thorium-232 is appearing in the thorium series.
What particles can thorium emit?
Alpha particles but also electrons and gamma radiations (Th 232).
What is thorium decay chains?
The decay chain of Th-232 contain Rn, Ra, Ac, Po, Bi, Po, Tl; the last isotope in the series is Pb-208 - stable.
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.
How many neutorns does thorium have?
Thorium-232 has 142 neutrons; the number of neutrons differ for each isotope.
