(Creationists claim that argon escape renders age determinations invalid.

However, any escaping argon gas would lead to a determined age younger, not older, than actual.

It can be readily seen from the plots that when this procedure is followed with different amounts of Rb87 in different minerals, if the plotted half life points are connected, a straight line going through the origin is produced. The steeper the slope of the isochron, the more half lives it represents.

When the fraction of rubidium-87 is plotted against the fraction of strontium-87 for a number of different minerals from the same magma an isochron is obtained.

The two curves cross each other at half life = 1.00. At half life = 2.00, Rb87 = 25% and Sr87 = 75%, and so on. 131, Strahler, Science and Earth History: Points are taken from these curves and a plot of fraction Sr-87/Sr-86 (as ordinate) vs. It turns out to be a straight line with a slope of -1.00.

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.

The creationist "argon escape" theory does not support their young earth model.) The argon age determination of the mineral can be confirmed by measuring the loss of potassium.

In old rocks, there will be less potassium present than was required to form the mineral, because some of it has been transmuted to argon.
