Episode 1: Out of Thin Air (1754-1806) One of science’s great odd couples — British minister  Joseph Priestley  and French tax administrator  Antoine Lavoisier  — together discover a fantastic new gas called oxygen, overturning the reigning theory of chemistry and triggering a worldwide search for new elements. Soon caught up in the hunt is science’s first great showman, a precocious British chemist named  Humphry Davy ,  who dazzles London audiences with his lectures, introduces them to laughing gas and turns the battery into a powerful tool in the search for new elements.Click next to watch. Mystry of Matter : Episode 1 Episode 2: Unruly Elements (1859-1902) Over a single weekend in 1869, a young Russian chemistry professor named  Dmitri Mendeleev  invents the Periodic Table, bringing order to the growing gaggle of elements.

Chemistry, a branch of physical science, is the study of the composition, properties and change of matter.Chemistry is chiefly concerned with atoms and their interactions with other atoms - for example, the properties of the chemical bonds formed between atoms to create chemical compounds. As well as this, interactions including atoms and other phenomena - electrons and various forms of energy - are considered, such as photo chemical reactions, oxidation-reduction reactions, changes in phases of matter, and separation of mixtures. Finally, properties of matter such as alloys or polymers are considered. Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other. Chemistry is a branch of physical science but distinct from physics. The etymology of the word chemistry has been much disputed. The genesis of chemistry can be traced to certain practices, known as alchemy, which had been pra...
