☆☆☆☆☆Radioactive dating is a technique used to find how old an object is.
One such example is potassium-argon dating, where potassium decays into argon. The proportion of potassium to argon suggests how old the object in question is.
An equation used is t = (1/c)Ln(1+(D/P)) Where c is the decay constant D is number of daughter atoms (number decayed) P is the number of parent atoms (number undecayed) t is the age of the object.
Another common technique in dating an object is carbon dating. Because the amount of carbon-14 has remained roughly constant through time on the earth it is possible to calculate the age of an object by finding the proportion of carbon-14 to carbon-12.
There is a suspicion that the relative abundance of carbon-14 could be changing due to the thinning of the ozone layer. The amount of carbon-14 depends on the amount of radiation permeates the ozone and thus the amount could be changing. Not proven, only a hypothesis.
Accuracy radioactive dating is called radiometric dating. This is taught in biology.
the strong nuclear force is more than 100 times greater than the electric force.
Temperature is the measure of average kinetic energy of all the atoms and molecules in an object
It loses mass.
It has a very long half-life. Disposal of radioactive waste is the biggest problem. Proper disposal is essential to ensure protection of the health and safety of the public and quality of the environment including air, soil, and water supplies.
As both fuels undergo reactions, heat is released, which is used to do work.
The age of an object that was once living.
It tells how long it takes for a radioactive isotope to become a daughter element.
20 years
The mass of a nucleus is subtracted from the sum of the masses of its individual components.
An alpha particle being emitted would result in a transmutation.
70 protons, 98 neutrons
Radioactive decay is the spontaneous breakdown of a nucleus into smaller parts.
4.5 × 1015 J
the ratio is 1.3 x 10^(-12)
Beta decay
the splitting of a nucleus
