Thorium, with the chemical symbol Th, is the chemical element with the atomic number 90.
The atomic weight (not mass) of thorium is 232,0377(4).
The neutral atom of thorium has 90 electrons.
Thorium has a number of isotopes. A common one is Thorium 234. So its mass number would be 234. Its atomic number is 90.
Thorium has 90 electrons.
The mass number of 232Th is 232.
The mass number of 232Th is 232.
232Th has 142 neutrons and 90 protons and electrons.
Thorium (Th).
Thorium, or Th, has an atomic number of 90. That means that every atom of thorium has 90 protons. The only naturally abundant isotope of thorium is 232Th, and so therefore it has 232 - 90 = 142 neutrons.
