Radioactive dating using potassium argon

It has the same number of protons, otherwise it wouldn't be uranium.

The number of protons in the nucleus of an atom is called its atomic number.

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

For example, uranium-238 is an isotope of uranium-235, because it has 3 more neutrons in the nucleus.

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.

By "age" we mean the elapsed time from when the mineral specimen was formed.

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.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.
