Who discoverd radioactive dating

It consists of a nucleus of two protons and neutrons, and two electrons in atomic orbits.The most common form is Helium-4, which is believed to be the product of Big Bang nucleosynthesis. This event is believed to have produced the majority of helium-4, along with small amounts of the hydrogen, helium and lithium isotopes.

The most recently discovered form of carbon is graphene, which consists of a single layer of carbon atoms arranged in hexagons.It became recognized as an element in the 17th century, after Robert Boyle classified an element as a substance that could not be decomposed into simpler substances.Carbon was named by French scientist Antoine Lavoisier as he carried out a variety of experiments to reveal its properties.This is due in part to its very high nuclear binding energy, plus the fact that is produced by both nuclear fusion and radioactive decay.And yet, scientists have only been aware of its existence since the late 19th century.
