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.
What is the only way to change one element into a different element?
through radioactive decay
What is the process by which some substances spontaniously emit radiation?
All elements with an atomic number >83 are naturally radioactive
Process which unstable nuclei emit radiation is called?
This process through which unstable nuclei emit radiation is called radioactive decay. It also is called nuclear decay, and it is a natural process in which an atom of an isotope decomposes into a new element.
Two types of heat in are earth?
radioactive decay and residual heat
What does the half life of a radioisotope correspond to?
The length of time required for half of a sample of radioactive material to decay
What is the name for the emission of rays and particles by a radioactive material?
The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
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 counts radioactive material?
We often use a Geiger counter to detect and count the decay of radioactive material.
Does alpha decay naturally?
Yes, alpha decay occurs naturally, that is why radioactive material is dangerous, because we can't simply "turn off" the radioactive decay.
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.
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.
What is the source of heat in the Earth interior?
The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.
What happens to a radioactive material over time?
It disintegrates into its daughter nuclei that are much more stabler than the radioactive nuclei. If a sample of radioacictive material is left it will decay into another element over a period of time. Note that complete decay is not possible. A fraction of the original radioactive material will always remain in the sample.
How is radioactive decay useful in dating rocks and minerals?
Radioactive decay has a constant rate of change, therefore it con be used to somewhat accurately tell the age of an object if you work backwards through the use of half-lifes (half of the existing radioactive material decays, leaving half of the original in its original form)
What does a half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
What does the half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
