These are the surfaces that we can get absolute ages for.For the others, one can only use relative age dating (such as counting craters) in order to estimate the age of the surface and the history of the surface.When the number of neutrons is not in balance with the protons then the atom of that particular element is said to be unstable.In nature, all elements have atoms with varying numbers of neutrons in their nucleus.
The effects of impacts and how they might affect us here on Earth, global climate change (Venus vs.
These differing atoms are called isotopes and they are represented by the sum of protons and neutrons in the nucleus. Carbon has 6 protons in its nucleus, but the number of neutrons its nucleus can host range from 6 to 8.
We thus have three different isotopes of carbon: Carbon-12 with 6 protons and 6 neutrons in the nucleus, Carbon-13 with 6 protons and 7 neutrons in the nucleus, Carbon-14 with 6 protons and 8 neutrons in the nucleus.
Once the half life of an isotope and its decay path are known, it is possible to use the radioactive decay for dating the substance (rock) it belongs to, by measuring the amount of parent and daughter contained in the sample.
An important point is that we must have an idea of how much of the daughter isotope was in the sample before the decay started.
