Thorium-232 decays by kicking out a helium nucleus, two protons and two neutrons, becoming radium-228. One of those neutrons decays, sending out an electron and turning into a proton.

There’s nothing like a http://thoriumremix.com FISSION is the splitting of an atom into two smaller atoms. It is the means by which nuclear power plants generate electricity. Carl In the radioactive decay cycle of Thorium, how many protons and how many neutrons are lost when Thorium-232 decays to Lead-206?

Thorium is a chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure. The chemical symbol for Thorium is Th. Atomic Mass of Thorium. Atomic mass of Thorium is 232.0381 u. Se hela listan på world-nuclear.org Thorium-234 has 90 protons and 144 neutrons with a total atomic mass of 234 As Thorium-234 undergoes beta decay, a neutron becomes a proton. The atomic number goes up one as the new element has an additional proton. For example, plutonium-239 converts thorium-232 to plutonium-239, which can be used to power another breeder reactor.
