What types of nuclear forces determine the rate at which a radioactive material decays?
Nuclear decay is not affected by physical conditions, therefore nothing can speed it up or slow it down. It is impossible to predict when a particular atom will decay, but given the number of atoms and their half life the total number number of decays can be predicted. Radioactivity is measured in becquerels (Bq). One becquerel equals one decay per second. Half life is the time taken for half of the unstable nuclei to decay.

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 do radioactive rocks generate electricity?
Radioactive rocks generate electricity through a process called nuclear fission. When the radioactive material decays, it releases energy in the form of heat. This heat is used to boil water and produce steam, which drives turbines to generate electricity.
Each of the objects below has a different amounts remaining of the original radioactive material X. Which object is most likely the oldest?
The object with the smallest amount of original radioactive material X remaining is most likely the oldest. Over time, radioactive material decays at a consistent rate, so the object with the least remaining material has been decaying the longest.
How does radiocarbon dating work to determine the age of organic materials?
Radiocarbon dating measures the amount of carbon-14 in organic materials to determine their age. Carbon-14 is a radioactive isotope that decays at a known rate over time. By comparing the amount of carbon-14 in a sample to the amount in the atmosphere, scientists can calculate the age of the material.
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.

Radioactive decay is when unstable atoms?
give off nuclear radiation
What is the percentage of radioactive nuclei left after 3 half lives have passed?
12.5%
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.
Two grams of radioactive material has a half life of one year After 3 years how much material is left?
3 grams. material decays into more stable elements, does not disappear.
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 is the term for an atom the decays?
unstable, radioactive
Is there radioactive plutonium?
Yes, plutonium-239 is a radioactive isotope commonly used in nuclear reactors and weapons. It decays through alpha particle emission, and its radioactivity poses significant health risks if not handled properly.
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.
Each of the objects below has a different amounts remaining of the original radioactive material X. Which object is most likely the oldest?
The object with the smallest amount of original radioactive material X remaining is most likely the oldest. Over time, radioactive material decays at a consistent rate, so the object with the least remaining material has been decaying the longest.
Is berkelium radioactive?
heck yeah it is so radioactive I almost pooped my pants
