Uses isotopes carbon dating

Others are 'unstable' or radioactive since their nuclei change over time through the loss of alpha and beta particles.The attributes of naturally decaying atoms, known as ‘radioisotopes’, give such atoms several applications across many aspects of modern day life.

Carbon is unique in its chemical properties because it forms a number of components superior than the total addition of all the other elements in combination with each other.

The biggest group of all these components is the one formed by carbon and hydrogen.

Elemental carbon exists in two well-defined allotropic crystalline forms: diamond and graphite.

Other forms with little crystallinity are vegetal carbon and black fume.

2) To familiarize students with the concept of half-life in radioactive decay.

3) To have students see that individual runs of statistical processes are less predictable than the average of many runs (or that runs with relatively small numbers involved are less dependable than runs with many numbers).

For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.

By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.

It wasn't until well into the 20th century that enough information had accumulated about the rate of radioactive decay that the age of rocks and fossils in number of years could be determined through radiometric age dating.
