Physics answers half life and radioactive dating


Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements.By "age" we mean the elapsed time from when the mineral specimen was formed.As the activity of a sample is proportional to the number of radioactive nuclides present it is also possible to say that the half-life is the time taken for half of the radioactive nuclides in a sample to decay.

C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.

People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.

Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. The most well-known of all the radiometric dating methods is radiocarbon dating.

Carbon-14 can yield dates of only “thousands of years” before it all breaks down.

An atom with the same number of protons in the nucleus but a different number of neutrons is called an isotope.
