Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

in the structure of the nuclei of atoms. Nuclear energy was discovered in the mid-twentieth century and first utilized in a military capacity in the atomic bombings of Hiroshima and Nagasaki. It all started rather innocently in 1896‚ when Antoine Henri Becquerel discovered radioactivity in Uranium. The next step came in 1902 when Marie and Pierre Curie isolated radioactive metal called Radium. In 1934‚ Enrico Fermi of Italy disintegrated heavy atoms by spraying them with neutrons.

In 1896‚ Henri Becquerel discovered that a sample of uranium was able to expose a photographic plate even when the sample and plate were separated by black paper. He also discovered that the exposure of the plate

The image of an illuminated object outside the room passed through the hole and was reproduced‚ upside down and in small scale‚ on an opposite wall. (2002.)
