Is Thorium-234 Proactinium-234 -1 a alpha decay equation?

Answer 1

It's beta decay. Actually, it's beta minus decay. A neutron in the nucleus of thorium-234 undergoes beta minus decay and changes into a proton with the subsequent release of an electron, an antineutrino and some energy. The transformation of a neutron in the thorium nucleus into that proton creates another element. You'll recall that the identity of an element is determined solely by the number of protons in its nucleus. And our thorium atom has now become a protractinium-234 atom.

Answer 2

Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234. Uranium-234 decays by alpha emission to Thorium-230, which then decays by alpha emission to Radium-226, then to Radon-222, again by alpha decay. After several more alpha and beta decays resulting in various isotopes of polonium, astatine, bismuth, thallium, and lead, the series ends with the stable isotope lead-206.

Answer 3

A) Beta Decay - As the mass number is the same and it has a charge of -1 B) Fusion - Because the resulting pruduct has a greater mass number nad atomic number than the 2 reactants C) Alpha Decay - As the mass number has dropped by 4 and there is a helium particle present (the product released through the process of alpha decay)

Answer 4

U238 is actually extremely stable with a half life of 4.468 billion years. But of the little that does decay, it decays like this...

U238 -> Th234 + He4 + 4.267 MeV

This is done through alpha decay.

Answer 5

No, 234Th decays to 234Pa via beta decay. If it DID decay via alpha emission, it wouldn't decay to 234Pa, because it would lose 4 Atomic Mass units, bringing it down to 230Ra, which as far as I know doesn't exist.

Answer 6

It is an example of beta decay, specifically beta-minus decay, in which a nucleus emits an electron and a neutron turns into a proton. The addition of another proton changes the atom of one element into an atom of a different element. When an atom of thorium-234 undergoes beta-minus decay, it emits an electron and it gains a proton, producing a protactinium-234 atom as a result. Its atomic number is 59, whereas the atomic number of thorium is 58.
