Relationship between radioactive isotope and radioactive dating
If they can begin to comprehend that it is random and spontaneous, they end up feeling less nervous about the whole thing.Radioactive decay involves the spontaneous transformation of one element into another.As radioactive isotopes of elements decay, they lose their radio activity and become a brand new element known as a daughter isotope.
The lifetime units are time units such as seconds or years.
One way that helps scientists place fossils into the correct era on the Geologic Time Scale is by using radiometric dating.
Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.
Radioactivity and radioactive decay are spontaneous processes.
Students often struggle with this concept; therefore, it should be stressed that it is impossible to know exactly when each of the radioactive elements in a rock will decay.
Statistical probablity is the only thing we can know exactly.
