Isotopes used dating archaeological finds

It was produced in 1934 by bombarding aluminium with - particles, i.e., Phosphorus - 30 was produced, together with a neutron.

All isotopes of a substance have the same chemical properties and behave in an identical manner.

The advantage of a radioisotope is that its position can be detected very easily by the radiation which it emits.

Naturally occurring radioactive substances have high nucleon number.

It is possible to make artificial radioactive substances by bombarding lighter nuclides with - particles, protons or neutrons.

It is reasonable to assume that equilibrium has been reached between the rate at which carbon - 14 forms in the atmosphere and the rate at which it decays, and that the amount of it in the atmosphere is constant.

When plants photosynthesise they take in CO from the air.The reaction is The sodium decays with the emission of a - particle.OR The important point is that it is now possible to produce any radioisotope.Radiocarbon or C -14, is a radioactive isotope of carbon.It is used to determine the age of fossils and other ancient organic matters.Thus, the length of time a specimen has been dead may be determined by the activity of the C - 14, which remains in it.
