Calculate radioactive dating

Nuclear Chemistry Half-Lives and Radioactive Dating - It mht be 1 gram, kilogram, 5 grams-- whatever it mht be-- whatever we start with, we take e to the negative k times 1.25 billion years. So you get the natural log of 1/2-- we don't have that N0 there anymore-- is equal to the natural log of this thing. A useful application of half-lives is radioactive dating. important because it enables you to determine when a sample of radioactive material is safe to handle.

Radiometric Dating - YouTube The natural log is just saying-- to what power do I have to raise e to get e to the negative k times 1.25 billion? k is equal to the natural log of 1/2 times negative 1.25 times 10 to the ninth power. Calculate the age of a sample using radiometric dating.

BBC - GCSE Bitesize More radioactive dating - hher tier So the natural log of this-- the power they'd have to raise e to to get to e to the negative k times 1.25 billion-- is just negative k times 1.25 billion. And then, to solve for k, we can divide both sides by negative 1.25 billion. And what we can do is we can multiply the negative times the top. Finally, after a series of radioactive isotopes are formed it becomes lead-206, which is stable. The age of the rock can be calculated if the ratio of uranium to lead.
