The process of radioactive dating

Members of the series are often called actinides, although actinium (at. 89) is not always considered a member of the series......

To demonstrate that the rates of decay of unstable nuclei can be measured, that the exact time that a certain nucleus will decay cannot be predicted, and that it takes a very large number of nuclei to find the rate of decay.

Since radioactive decay is a random process, the decay of a single nucleus may happen at any time but for many undecayed nuclei, the average decay rate is given by the decay constant, λ and it has the unit of [s.

On the basis of our reasoning above we can say that the number which will decay will depend on overall number of nuclei, N, and also on the length of the brief period of time.

Geological processes have helped to create many iconic features on Earth.

Processes, such as plate tectonics, are what shapes the face of the Earth.

The name 'radioactive' may suggest to you that radioactive elements radiate radio waves, but unfortunately that is not so!

The name 'radioactivity' is a misnomer because these elements have nothing to do with radio waves! To understand radioactivity, we need to explore the structure of an atomic nucleus.

The is a measure of how quickly on average a radioactive nuclei will take to decay.Geology is the study of the composition and physical properties of rocks, minerals, gems and other related earth materials, including diamonds and crystals.Scientists gain an understanding of the Earth's history by studying its composition.Since its radioactivity presents a serious health hazard (see radiation sickness), disposing of such material is a great problem......actinide series,a series of radioactive metallic elements in Group 3 of the periodic table.
