Can scientist use the isotope c-14 to date granite?
Yes because they look at the ammount of radioactive decay and they can determine the age of the granite. As the radioactive isotope decreases the non radioactive element increases. The less radioactive decay ammount there is the older it is.
What is non radioactive decay?
Radioactive decay is the spontaneous change or disintegration of an unstable atomic nucleus as it transforms itself to lose energy. It does this by the release of either particulate radiation or electromagnetic radiation, or both. This atomic event is random and cannot be predicted, but by applying statistical principles to large numbers of a given radionuclide, an "average" decay time can be found, and we have the half-life. There are several different types of radioactive decay. They range from spontaneous fission to alpha decay, beta decay and a couple of others. The spontaneous breakdown of a nucleus
What happens to Iodine-125 brachytherapy seeds after decay?
Iodine-125 (53125I) decays by beta+ decay, with a half-life of 59.4 days, to tellurium-125 (52125Te), which is stable and non-radioactive.
In chemistry what is a half life?
The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The concept originated in describing how long it takes atoms to undergo radioactive decay but also applies in a wide variety of other situations.Half-lives are very often used to describe quantities undergoing exponential decay-for example radioactive decay-where the half-life is constant over the whole life of the decay, and is a characteristic unit (a natural unit of scale) for the exponential decay equation. However, a half-life can also be defined for non-exponential decay processes, although in these cases the half-life varies throughout the decay process. The converse for exponential growth is the doubling time.
Which is not radioactive beta rays gamma rays or X-rays?
Both beta rays and gamma rays are the products of radioactive decay and are the result of changes in atomic nuclei. X-rays can be generated by using high voltage to accelerate electrons and slam them into a metal target, so they might be said to be non-radioactive.
What element is nonradioactive in the chain decay of uranium?
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
What is the toxic radioactive metallic element that occurs in small quantities as a decay product of uranium?
All the decay chain isotopes are radioactive and toxic (excepting the last member which is non-radioactive but also toxic); you think probably to radium or polonium.
What could not be dated using carbon-14 radioactive decay?
material of non-organic origin
What does the half life of a radioisotope represent?
It tells what fraction of a radioactive sample remains after a certain length of time.
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.

Can a sample of matter change its composition or state?
For chemical reactions, the elements in a sealed vessel will not change. But, reactions can take place that would tend to take the sample to a state of equilibrium. Or, with heating or cooling the physical state can be changed.Another type of reaction is nuclear decay, in which radioactive substances will spontaneously decay to other radioactive substances, or decay to non-radioactive substances, thus actually changing the elements present.

Is the element sodium radioactive or non-radioactive?
non radioactive element
How does a sample of radioactive waste decay to a nonhazardous level?
All radioactive material has a characteristic half-life. This is a period during which half the matter from the original mass will have decayed into a daughter element. Either the daughter element is non-radioactive and therefore non-hazardous or it is radioactive and has its own half-life. The total radioactivity thus reduces over time and at some stage is deemed to reach a non-hazardous level.
What product contain unum bium?
I assume you mean unuNbium, now officially named Copernicium. It is an extremely radioactive element with atomnumber 112. Based on the atomnumber this element is the product of any successful fusion reaction between elements that add up to this number or the decay of any higher even numbered element. I say even because the emitted radioactive alpha radiation is a hydrogen core consisting of two protons. The decay will then continue to jump over each second element until it reaches a stable non radioactive element.
