No he did not. Carl Wilhelm Scheele discovered it, but he wasn't sure if it was a new element or not. After he died Sir Humphry Davy figured out that chlorine was in fact a new element. How old are asker? I'm twelve.
Sir Humphry Davy isolated the element potassium in 1807 by using electrolysis to extract it from caustic potash (potassium hydroxide).
Yes he did and he built Trelissick house in Cornwall in 1790
Sir Humphrey Davy discovered potassium in 1807 by isolating the element from potassium hydroxide using electrolysis. He used a voltaic pile to pass an electric current through the compound, leading to the isolated element being deposited on a cathode.
Sir Humphry Davy did not invent iodine. Iodine was discovered by French chemist Bernard Courtois in 1811. Davy was instrumental in the development of the miner's safety lamp.
Chlorine gets its name from the Greek word "chloros," meaning greenish-yellow, which describes its color and properties as a gas. It was named by Sir Humphry Davy in 1810.

It is not known where exactly in England sodium was discovered. It was discovered by Sir Humphrey Davy in 1807.
