Q:

Where was sodium discovered?

A:

Sodium was discovered at the Royal Institution in England by Sir Humphry Davy. Davy isolated sodium in 1807 through the electrolysis of sodium hydroxide. He used electrolysis to isolate other elements such as potassium, barium and magnesium.

Davy was a pioneer in the field of electrochemistry, which is the study of chemical changes associated with electricity. His greatest contribution to humanity is the Davy lamp, a safety lamp used by Newcastle coal miners. Newcastle mines contained methane gas that could be ignited by candles inside the miners' hats. The Davy lamp's wick is surrounded by metal gauze, which separates the flame from the gas.

    How was sodium discovered?

    A:

    Sodium was first isolated in 1807 by Humphrey Davy, one of the early luminaries of modern chemistry. The element was found, along with potassium, when Davy electrolyzed damp potash with soda. Prior to his discovery, these compounds were thought to be elements themselves, as they resisted decomposition.

    How was fluorine discovered?

    A:

    French scientist Henri Moissan discovered fluorine in 1886 when he ran electric currents through hydrogen fluoride, a compound that contains fluorine. With his discovery, he solved a puzzle that had brought injury and even death to earlier chemists trying to isolate this halogen gas, according to Chemistry Explained.
