After the IUPAC rule: 232Th, etc.
Also used: Th-232, thorium-232
For example a thorium isotope is Th-231 or 23190 Th.
When uranium undergoes alpha decay, it emits an alpha particle (which is equivalent to a helium nucleus, ( ^4_2He )), resulting in a decrease of its atomic number by 2 and its mass number by 4. For example, if uranium-238 (( ^{238}{92}U )) undergoes alpha decay, it transforms into thorium-234 (( ^{234}{90}Th )). Thus, the notation for the thorium isotope produced is ( ^{234}_{90}Th ).
The electron configuration of thorium is: [Rn]6d27s2.
Thorium has 90 protons. It does not matter which isotope is involved.
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
For example a thorium isotope is Th-231 or 23190 Th.
Thorium-232 is typically indicated with the notation "Th-232."

Unfortunately WikiAnswers doesn't accept subscript/superscript.For the isotope thorium-232: 232Th90232 is a superscript (mass number) and 90 is a subscript (atomic number).
- After alpha disintegration the isotope uranium-238 is transformed in the isotope thorium-234. - After alpha disintegration the isotope uranium-235 is transformed in the isotope thorium-230. Platinum is a misspelling ?
Thorium B is 212Pb: radioactive isotope of lead. Thorium D is 208Pb: stable isotope of lead.
Thorium has 90 protons. It does not matter which isotope is involved.
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
In this type of nuclear reactor the fertile isotope thorium-232 is transformed in the fissile isotope uranium-233 and this act as a nuclear fuel.
Thorium-232 has 142 neutrons; the number of neutrons differ for each isotope.
The atomic number of thorium is 90. so it will always have 90 protons in all its isotope.
