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.

What is the relationship between time and the decay of radioactive substances as shown in the graph of radioactive decay?
The relationship between time and the decay of radioactive substances is shown in a graph of radioactive decay by demonstrating how the amount of radioactive material decreases over time. This decay occurs at a consistent rate, known as the half-life, which is the time it takes for half of the radioactive material to decay. The graph typically shows a gradual decrease in the amount of radioactive substance as time progresses, following an exponential decay curve.
How can the rate of radioactive decay change over time?
The rate of radioactive decay can change over time due to factors such as the type of radioactive material, environmental conditions, and any external influences. The decay rate is generally constant for a specific radioactive isotope, but it can be affected by changes in temperature, pressure, or chemical reactions. Additionally, the decay rate can also be influenced by the presence of other radioactive materials or particles that may interact with the original material.
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 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 you explain the half-time of a radioactive material?
The half-life of a radioactive material is the time it takes for half of a sample of the substance to decay. It is a characteristic property of the specific radioactive isotope and is used to determine the rate of decay and the stability of the material. The half-life can vary greatly depending on the isotope, ranging from fractions of a second to billions of years.
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 happens to the radioactive isotopes that are released in a nuclear reaction?
they decay over time

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.

Over time what will happend to the radioactive atom?
They experience radioactive decay. They emit radiation, changing the state of their nucleus, usually by the loss of protons and neutrons. However, this process is completely random; it can only be predicted as a half-life, or the amount of time it takes half of a certain material to decay. This does not predict when an individual atom will decay, it only predicts when approximately half of the material will have decayed.

The half-life can vary greatly depending on the isotope, ranging from fractions of a second to billions of years.
What general pattern is found on a graph of radioactive decay?
A general pattern found on a graph of radioactive decay is that the number of radioactive atoms decreases exponentially over time. The graph typically shows a steep initial drop followed by a gradual decrease as the radioactive material decays.
What does it mean when radioactive decay hasn't started yet?
You can't just start or stop radioactive decay. A certain type of atom (a certain isotope) will basically ALWAYS decay at a certain rate. The statement might refer to what happens at time t = 0, i.e., before the material had time to decay.
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
