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.
How is the use of radioactive decay in absolute dating similar to how you us a clock?
every 12 is a half life aka look in the book idiot
What is the purpose of nuclear decay?
nuclear decay is when the nucleus of an atom is broken apart. because the number of protons has changed, so has the element. this usually happens with large nuclei, which tend to be more unstable (radioactive) than smaller nuclei.
What is the definition of radioactivity?
Radioactivity is a term that refers to the emissions from atomic nuclei due to changes in those nuclei. Those changes will occur as a result of instability of isotopes of certain elements. These atoms have a nuclear structure that is inherently unstable for whatever reason. And any unstable nucleus will eventually decay in a manner characteristic of that particular atom (radioisotope). We term the activity associated with the natural changes due to nuclear instability radioactive decay. As you can guess, different things might appear as an expression of the radioactivity of a radioisotope, and they'll vary according to the radioisotope being inspected.We could say that the elements on the upper end of the periodic table are radioactive, and these elements, the ones beginning with bismuth, have no nuclear configurations that permit them to avoid instability and their eventual radioactive decay. Additionally, we know that there are isotopes of other elements (lighter ones) that are not stable, and these radioisotopes are radioactive and will decay in time. Lastly, there are the elements technetium and promethium, which are the only elements with atomic numbers below that of bismuth that have no stable isotopes.The emissions we might gather under the umbrella of radioactivity include both particulate radiation and radiation in the form of energy, or electromagnetic radiation. Your investigation of the instabilities associated with atomic structure and what it is that results is just beginning. Use the links below to check facts and learn more.
What is the spontaneous breakdown of the atomic nucleus called?
We use the general term radioactive decay to identify the spontaneous breakdown of an atomic nucleus.
Process atoms use to become stable?
Radioactive decay
What counts radioactive material?
We often use a Geiger counter to detect and count the decay of radioactive material.
Use decay in a sentence?
The body had started to decay.
How do you use radioactive in a sentence?
Uranium is naturally radioactive.
What scientist suggested the use of radioactive decay to age the Earth?
Rutheford
How do you use radioactive as an adjective in a sentence?
You can just put something in the sentence that is going to be radioactive that's all.

What is radioactive half-life used for?
to determine how long it will take to half of nuclids to decay, having use in radioactive materials operations
What formula do you use for radioactive decay methods?
dA/dt= -KA and A=A0e^-Kt
How would you use decay in a sentence?
The teeth will slowly decay if you do not brush your teeth.
How do you use the word radioactive in a sentence?
That area will be radioactive for a long, long time.
