Who discoverd radioactive dating

Bombardment reactions can be used to produce very heavy elements, including many which don't occur in nature.

Carbon was first discovered in prehistoric times as charcoal.

Radioactive isotopes are prepared in the lab using bombardment reactions to convert a stable nucleus into one which is radioactive.

Positron (a particle with the same mass as an electron, but a charge of 1 instead of -1) emission isn't observed in natural radioactivity, but it is a common mode of decay in induced radioactivity.

Large amounts of new helium are being created all the time through this same process, where the heat and pressure at the core of stars are causing hydrogen atoms to fuse.

When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit.

For example: Gamma rays are high-energy photons with a very short wavelength (0.0005 to 0.1 nm).

The emission of gamma radiation results from an energy change within the atomic nucleus.

Gamma emission changes neither the atomic number nor the atomic mass.Fullerene was also called "buckminsterfullerene," because its molecules resembled the geodesic domes designed by architect Buckminster Fuller for the 1967 World's Fair.
