The nucleus of the atom decays, and in the process, the nucleus transforms into another element, or into an isotope or isomer of the same element. In radioactive decay, the nucleus always emits some kind of particle(s). It is the high-energy emission of these particles that we call radiation. There are many different types of radioactive decay:
- Alpha decay results in the emission of an alpha particle (two neutrons and two protons)
- Beta decay results in the emission of a beta particle (an electron or a positron)
- Neutron decay results in the emission of a neutron
- Proton decay results in the emission of a proton
- Gamma decay results in the emission of a gamma particle (a photon)
- Neutrino decay results in the emission of a neutrino or antineutrino
In some cases, a combination of the above emissions takes place. For example in double beta decay, a single nucleus emits two electrons and two antineutrinos in the same event.

DOES the radioactive decay of 14c produce carbon 12?
No. 14 6 carbon decays into 147 nitrogen.
Who discovered radioactive decay in 1898?
ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.
What makes a radio active decay chain end?
A radioactive decay chain ends when a series of radioactive isotopes transforms into a stable isotope, which no longer undergoes further decay. Each isotope in the chain decays into another isotope or element until a stable state is reached. Once the final stable isotope is formed, the chain ceases, as there are no further radioactive transformations. This stable isotope can exist indefinitely without undergoing radioactive decay.
What happens to radioactive materials if you do not use them?
That depends on the radioactive material. But whether you use it or not, the radioactive material will decay into other elements over the course of time. The time it takes for half of the material to decay into something else is called the "half-life". The more radioactive the substance is, the faster it decays. The half-life of a radioactive element can be measured from fractions of a second to billions of years.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
What are two different forms of radioactive decay?
Alpha and beta decays.
How can one determine the decay constant of a radioactive substance?
To determine the decay constant of a radioactive substance, one can measure the rate at which the substance decays over time. By analyzing the amount of radioactive material remaining at different time intervals, scientists can calculate the decay constant, which is a measure of how quickly the substance decays.
How does radioactive decay provide energy source for plate tectonics trough the decays of uranium thorium and potassium?
During radioactive decays heat is released and the center of the Earth is melted.
What element is obtained through the decay of radium?
Radium naturally decays into radon, which is a radioactive noble gas. This decay process is one of the steps in the radioactive decay chain of uranium-238.
Does strontium undergo radioactive decay?
Yes, strontium can undergo radioactive decay. One common isotope of strontium, strontium-90, is a radioactive isotope that decays through beta decay. It is a byproduct of nuclear fission and can be harmful to living organisms due to its radioactive nature.
What radioactive elements form when bismuth 214 deacys?
When bismuth-214 (Bi-214) undergoes radioactive decay, it primarily decays into polonium-214 (Po-214) through beta decay. Polonium-214 is also radioactive and further decays into lead-210 (Pb-210) via alpha decay. This sequence is part of the decay chain of uranium-238, where bismuth-214 is an intermediate product.
DOES the radioactive decay of 14c produce carbon 12?
No. 14 6 carbon decays into 147 nitrogen.
What is the sample of the radioactive isotope 131I decays its half-life?
Iodine-131 has a half-life of about 8 days.
What is a decay chain?
One element decaying into another, which decays into another
What is the definition for decay product ratio?
The decay product ratio is the ratio of the amount of a specific decay product to the amount of the parent isotope in a radioactive decay chain. It is used to determine the relative contribution of different decay pathways in the decay of a radioactive substance.
Does Carbon-14 naturally decays Carbon-12?
No, Carbon-14 naturally decays into nitrogen-14 through beta decay, not into Carbon-12. Carbon-12 is a stable isotope and does not undergo radioactive decay.
What is the stable isotope that results from the decay of radioactive elements?
The stable isotope that results from the decay of radioactive elements varies depending on the specific element undergoing decay. For example, uranium-238 decays to lead-206, while carbon-14 decays to nitrogen-14. These stable isotopes are often the end products of a decay chain, where a series of transformations ultimately leads to a stable state. Each radioactive element has its unique decay pathway and stable end products.
