What happens when an element undergoes radioactive decay?
|
After radioactive decay, the element changes into a different isotope of the same element or into an entirely different element.
|
|
|
How do scientists predict when an atom will undergo radioactive decay?
|
It is impossible to predict the moment when any particular nucleus will
decay, but it is possible to predict the time required for half of the nuclei in a given radioactive sample to decay. |
|
|
What holds the nuclei of atoms together?
|
The stability of a nucleus depends on the nuclear forces that hold the nucleus together. These forces act between the protons and the neutrons
|
|
|
What is released when the nucleus of a heavy atom is split?
|
In the fission process, when the nucleus splits, both neutrons and
energy are released. |
|
|
What happens when the nuclei of small atoms are joined?
|
Energy can be obtained when very light nuclei are combined to form heavier nuclei.
|
|
|
Where are we exposed to radiation?
|
We are continually exposed to radiation from natural sources, such as the sun, soil, rocks, and plants.
|
|
|
What are some beneficial uses of nuclear radiation?
|
Some common applications of nuclear radiation include medical diagnosis and treatment, smoke detectors, manufacturing, and agriculture.
|
|
|
How is the energy produced by nuclear fission used?
|
Energy produced from fission is used to provide electrical energy to
millions of homes and businesses. |
