Half-Life is the time taken for the radioactiverty of a source to half. For example Americium-241 (commonley used in smoke alarms) has a Half-Life of 432 Hope this helps Dynofly :-D

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.


What is necessary for you to be able to explain what happens during radioactive decay?

To fully explain radioactive decay you need quantum mechanics.


How to predict the mode of decay in radioactive substances?

To predict the mode of decay in radioactive substances, scientists use the concept of nuclear stability and the ratio of protons to neutrons in the nucleus. By analyzing these factors, they can determine whether a radioactive substance will decay through alpha, beta, or gamma decay.


What determines the type of radioactive decay that occurs?

Rutherford


Does radioactive decay occurs at a gradually changing rate?

no


What is a colorless naturally occurring radioactive inert gaseous element formed by radioactive decay?

It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.


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.


How can radioactive substances to be formed?

Through natural or facilitated decay processes.


Can any explain the formation of francium by the radioactive decay of uranium and actinium?

227Ac----- alpha decay---- 223Fr


Why are alpha beta gamma found in many radioactive substances?

They arent really found in the substance, they are a product of radioactive decay.


Radioactive decay occurs when?

When a radioactive element slowly turns into another element/s when it emits various particles.


What is the process by which some substances spontaniously emit radiation?

The process by which some substances spontaneously emit radiation is called radioactive decay. During this process, unstable atomic nuclei release particles (such as alpha or beta particles) or electromagnetic radiation (such as gamma rays) to achieve a more stable configuration.
