There must be more daughter isotopes than parent isotopes for a rock to be younger
According to radiometric dating the Earth is approximately 4.54 billion years old. This age is based on dating of meteorite material.
If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.Google radiometric dating.
The four types of radiometric dating are: Potassium, Uranium, Rubidium, and Carbon I hope thats the answer you were looking for:)

According to radiometric dating the Earth is approximately 4.54 billion years old. This age is based on dating of meteorite material.
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
Radiometric or isotopic dating.
If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.Google radiometric dating.
radiometric dating is base on the half life of the radioactive atoms
In most cases radiocarbon dating is the most commonly used method for dating an artifact made from a material which was once part of a living organism. However, there are other methods available. Although radiometric dating is a useful tool dendrochronology (also known as tree ring dating) remains the most effective and accurate method of dating certain species of wood (where a suitable sample can be found).
Radio metric dating.
Radiometric dating is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
