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.

alpha particles.


What element does thorium 230 decay when it emits an alpha particle?

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.


When a Uranium 238 emits an alpha particle the nucleus left behind has how many protons?

When a Uranium-238 emits an alpha particle, it loses 2 protons and 2 neutrons. The resulting nucleus, Thorium-234, has 90 protons.


What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?

When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.

What isotope is formed when uranium 235 emits an alpha particle?

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.
