Atomic Theory discovery john Dalton

In 1808, John Dalton discovered a way to link invisible atoms together to things that had measurable qualities, such as a mineral’s mass or the volume of a certain gas. In his theory, he stated that elements consist of small microscopic particles that are called atoms. His theory went on to state that a pure element only consists of identical atoms that have the same mass.

A walnut is the nut of any tree of the genus Juglans, particularly the Persian or English walnut, Juglans regia. Technically a walnut is the seed of a drupe or drupaceous nut, and thus not a true botanical nut. It is used for food after being processed while green for pickled walnuts or after full ripening for its nutmeat. Nutmeat of the eastern black walnut from the Juglans nigra is less commercially available, as are butternut nutmeats from Juglans cinerea. The walnut is nutrient-dense with protein and essential fatty acids.
