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 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 is a radioactive decay series and when does it end?
Usually called a 'decay chain', there is a series of radioactive decays which end with a stable isotope. Ex: uranium undergoes about 14 steps in the decay chain that ends with the formation of a stable isotope of Lead.
What are two different forms of radioactive decay?
Alpha and beta 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.
DOES the radioactive decay of 14c produce carbon 12?
No. 14 6 carbon decays into 147 nitrogen.
What is the process by which an element slowly decays over time?
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
What is an unstable nucleus that starts a decay process called?
A nucleus that starts to decay is called a radioactive nucleus or atom. It decays with a known and unique half life by several processes including but not limited to beta decay, alpha decay, electron capture decay, and positron emission.
When a radioactive nucleus decays and forms a new nucleus is the new nucleus always radioactive?
No. A stable nucleus can form. If the new nucleus is radioactive, then it will contiue to decay until a non radioactive nucleus is attained.
When radioactive decays stop?
It will stop when there is nothing left to decay. There is basically no way to stop certain nuclides (isotopes) from decaying.
Radioactive decay is when unstable atoms?
give off nuclear radiation

Do all radioactive isotopes follow the half-life single rate or are there those that decay at multiple rates throughout their decay?
In general, a radioactive substance decays at a constant rate throughout time. That is not to say that the same number of decays occur per unit time. They cannot, and this is because the sample is shrinking as radioactive decay "claims" more and more of it. The decays per second is decreasing. But the rate of decay remains constant. There are some instances where slight changes in decay rates of a couple of different radioactive substances occur when we put them in extreme magnetic fields. But, by and large, the decay rates of radionuclides are constant. Additionally, we've gone to great lengths in an attempt to induce changes in the decay rates of a number of radionuclides, but they've proved themselves sublimely resistant to any manipulation by the likes of us, even as clever as we are.
When elements such as uranium and plutonium decay do they form different elements chemical reactions or larger compounds?
When an element "decays", it forms a different element. This is the definition of "decay" when referring to radioactive elements.
What is the source of heat in the Earth's interior?
The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.
