What else can I help you with?
Radioactive decay is when unstable atoms?
give off nuclear radiation
Why does alpha and beta decay more commonly occur in radioisotopes?
Because the less protons are in an atom the quicker it decays.
What describes a radioisotope?
An isotope of an element that is radioactive
What is nuclei that has unstable decay known as?
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
Can gama radiation takes place before alfa and beta decay?
Yes. Each unstable element decays differently. Some emit gamma, some emit alpha, some emit beta, and some emit different combinations of those in different sequences as one unstable element gives rise to another unstable element.
What are the equations for each of the following radioactive decay reactions alpha emissions by thorium 228 and beta emissions by aluminum 28?
The equation for alpha decay of thorium-228 is 228Th -> 224Ra + 4He, where thorium-228 decays into radium-224 by emitting an alpha particle (helium nucleus). The equation for beta decay of aluminum-28 is 28Al -> 28Si + e + v, where aluminum-28 decays into silicon-28 by emitting a beta particle (electron) and an antineutrino.
What is the decay mode for 129xe that decays to 129I?
Beta
When C-14 beta decays the daughter nucleus is?
penis :)
What happens when a beta decays?
Every one comes in Tension..!
What particle is emitted when P-32 decays to S-32?
When P-32 decays to S-32, a beta particle is emitted. This beta particle is an electron released during the conversion of a neutron into a proton within the nucleus of the atom.
Why Uranium-238 decays into thorium-234?
All radioactive isotopes decay because they are unstable; uranium-238 decay to thorium-234 by beta (-) decay. The half life of 238U is very great: 4,468.109 years.
What type of radiation is emitted when carbon 14 is decays?
Carbon-14 decays by beta-, which emits a W- boson that immediately decays into an electron and an electron anti-neutrino.
