After the IUPAC rule: 232Th, etc.
Also used: Th-232, thorium-232
A number (usually in superscript) before the element's symbol is the atomic weight. Different numbers here indicate different isotopes.
For example a thorium isotope is Th-231 or 23190 Th.
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.
The electron configuration of thorium is: [Rn]6d27s2.
An isotope of thorium is obtained.
For example a thorium isotope is Th-231 or 23190 Th.
Th-234
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.
Thorium is not used for the stress test.
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
The electron configuration of thorium is: [Rn]6d27s2.
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.
