Examples of chemical changes:
combustion

New method to separate much-needed medical isotopes proposed
However, if you aristocrat closely enough into the atoms , there are subtle differences that can have very big effects. These "different" atoms, called isotopes, are heavily relied on in areas of prescription and nuclear energy and now researchers have proposed a novel way of isolating them.
Reported today, Wednesday 29 February, in the New Daily of Physics , this new proposal combines a simple laser with a set of specifically aligned magnets to develop the desired atoms, and offers an alternative to the only general-purpose separator, called a Calutron, which is currently operating in Russia.
The Calutron, first invented by Ernest Lawrence in the 1930s, is still old to separate most elements in the periodic table; however, the US government has made it clear in its recommendations that the smashing is facing a supply crisis that the Russian Calutron cannot resolve.
Consequence Raizen, lead author of the study and Professor of Physics at the University of Texas at Austin, said: "One element is clear: isotopes are indispensable to the advancement of medicine. Calcium-48, for specimen, is used in the diagnosis of osteoporosis and bone development in children and nickel-64, which can be converted to copper-64, is a cheering isotope for imaging and cancer therapy.
