Discovery

This gives the date, where known, of the discovery of the element, together with the discoveror and place of discovery.

Image showing periodicity of the chemical elements for discovery in a circular periodic table heatscape style. — Image showing periodicity of the chemical elements for discovery in a spiral periodic table heatscape style.

Image showing periodicity of the chemical elements for discovery in a 3D spiral periodic table column style in which the height of the column is proportional to the property.

Image showing periodicity of the chemical elements for discovery in a 3D spiral periodic table column style in which the height of the column is proportional to the property. — Image showing periodicity of the chemical elements for discovery in a 3D spiral periodic table column style in which the height of the column is proportional to the property. The only differences between this picture and that above are the colours of the background and the base.
