When a radioactive isotope of an element releases a radiation particle the sub-atomic structure of it's nucleus changes. If an alpha particle is released the nucleus loses 2 protons and 2 neutrons, making it a new, lighter and smaller atom and therefore a different element. If a beta particle is released one of the neutrons in the nucleus releases an electron and becomes a proton so the atom's mass does not change significantly but t does become a different element.
What else can I help you with?
How is the radioactive decay of Krypton different from the radioactive decay of Americium?
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
Who discovered radioactive decay in 1898?
ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.
What is the radioactive decay law?
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
What is necessary for you to be able to explain what happens during radioactive decay?
To fully explain radioactive decay you need quantum mechanics.
Use the term radioactive decay in a sentence?
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."
What are advantages of radioactive decay?
One reason is that radioactive decay heats the earths interior
The age of the earths crust can best be determined from the studies of A the salts of the oceans B the type of fossils left behind C erosion from a river D radioactive decay E surface weatherin?
Radioactive decay
Could the amount of some elements in earths crust increase?
Yes. That is what causes some of the Earths core heat. Elements being formed by radioactive decay. Look at the Earths' makeup and see that the percentages of elements follows the periodic chart by decay.
What is the change in the earths temperature?
radioactive decay
Could the amount of elements in Earth's crust increase?
Yes. That is what causes some of the Earths core heat. Elements being formed by radioactive decay. Look at the Earths' makeup and see that the percentages of elements follows the periodic chart by decay.
How does the temperature change from the crust to earth to the core?
Radioactive decay!
How does the temperature change from the crust to earth's core?
Radioactive decay!
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.
Is it hot in the earths mantle?
Decay of radioactive elements in the mantle heats it.
Can geothermal energy be exhausted?
yes, to a certain extend. The rock is cooled by the thermal extraction. It will slowly warm up again from radioactive decay (fission) in the earths core and crust.
Decaying uranium atoms in the earths crust are what?
Decaying uranium atoms in the Earth's crust are radioactive and release energy in the form of alpha, beta, and gamma radiation as they decay. This process occurs at a constant rate known as the half-life of uranium. The decay of uranium atoms plays a significant role in the geologic processes and the formation of Earth's natural resources.
How do radioactive isotopes add to earths heat?
Radioactive isotopes, such as uranium and thorium, undergo radioactive decay, releasing energy in the form of heat. This heat contributes to the overall heat budget of Earth. Radioactive isotopes are present in the Earth's crust and mantle, and their decay helps maintain the planet's internal heat flow.
