Thorium chemical because it is an element on the Periodic Table. However, it can produce a nuclear reaction.
Alpha emission means a He (A=4, Z=2) core is released along with energy. Helium's atomic number is 2 and the atomic mass is 4. So when Thorium (A=x, Z=90) emits an alpha particle it becomes a Radium (A=x-4, Z=88). By the way: Thorium is very vague when it comes to nuclear physics. It's important to state the atomic mass of the atom. There exist many forms of each element, called isotopes.
When a Uranium-238 emits an alpha particle, it loses 2 protons and 2 neutrons. The resulting nucleus, Thorium-234, has 90 protons.
alpha particles.
When 60Co decays by beta- decay it produces 60Ni.
Yes, a glow stick is considered a luminous object because it emits light through a chemical reaction.
The nuclear reaction is: 232Th--------------- 228Ra + α
Thorium-230 decays into radium-226 when it emits an alpha particle.
The nuclear reaction is: 232Th--------------- 228Ra + α
The resulting element is protactinium, atomic number 91.
Uranium-235 decays primarily through alpha decay, where it emits an alpha particle (helium nucleus) and transforms into thorium-231.
When thorium-230 decays by emitting an alpha particle, it transforms into radium-226. This decay process reduces the mass number by 4 and the atomic number by 2.

alpha particles.
You get this answer by performing the following: Mass # Mass # 4 Atomic # Parent symbol -> Atomic # Daughter symbol + 2 He 238 234 4 92 U -> 90 Th + 2 He Both sides must equal the same thing, so if you figure out what plus 4 = 238 and what plus 2 = 92, you can figure out the element is formed through decay. The resulting element in this case is Thorium.
When californium emits an alpha particle, it creates curium.
This is how Polonium 218 gets here: It is constantly being formed. The Universe is Billions of years old. If there is a God then he is much greater than "Creationists" could ever imagine.Start with a uranium-238 atom. This atom has 92 protons and 146 neutrons. It has a half-life of 4.5 billion years. When it decays it emits an alpha particle, leaving behind a thorium-234 atom.A thorium-234 atom has 90 protons and 144 neutrons. It has a half-life of 24.5 days. When it decays it emits a beta particle and a gamma ray, leaving behind a protactinium-234 atom.A protactinium-234 atom has 91 protons and 143 neutrons. It has a half-life of 269,000 years. When it decays it emits a beta particle and a gamma ray, leaving behind a thorium-230 atom.A thorium-230 atom has 90 protons and 140 neutrons. It has a half-life of 83,000 years. When it decays it emits an alpha particle and a gamma ray, leaving behind a radium-226 atom.A radium-226 atom has 88 protons and 138 neutrons. It has a half-life of 1,590 years. When it decays it emits an alpha particle and a gamma ray, leaving behind a radon-222 atomradon-222, with a half-life of 3.825 days, emits an alpha particle to become polonium-218.polonium-218, with a half-life of 3.05 minutes, emits an alpha particle to become lead-214.lead-214, with a half-life of 26.8 minutes, emits a beta particle and a gamma ray to become bismuth-214.bismuth-214, with a half-life of 19.7 minutes, emits either an alpha particle or a beta particle and a gamma ray to become either thallium-210 or polonium-214.polonium-214, with a half-life of a 150 microseconds, emits an alpha particle to become thallium-210.thallium-210, with a half-life of 1.32 minutes, emits a beta particle to become lead-210.lead-210, with a half-life of 22 years, emits a beta particle and a gamma ray to become bismuth-210.bismuth-210, with a half-life of five days, emits a beta particle to become polonium-210.polonium-210, with a half-life of 138 days, emits an alpha particle and a gamma ray to become lead-206.lead-206 is a stable isotope of lead.Answer: The experiment performed by the creationist Robert Gentry about the existence of polonium halos found in granite yielded inconclusive results. Robert Gentry does not have any evidence that the halos are indeed a result of polonium isotopes decaying.
