Credit for discovering silicon is given to Swedish chemist Jöns Jakob Berzelius, who reacted potassium fluorosilicate with potassium to produce amorphous silicon, which he named silicium, a name first proposed by Sir Humphry Davy in 1808. The name derives from the Latin words silex or silicis, which mean "flint". Selenium in the periodic table; Symbol: Se: Atomic number: 34: Group: 16: Period: 4: Block: p: Element category: Nonmetal: Physical properties; Phase at STP: Solid: Density: 4.81 g/cm 3: Atomic weight: 78.9718 u: Melting point: 494 K 220.85 °C 429.53 °F: Boiling point: 958 K 684.85 °C 1264.73 °F: Atomära egenskaper; Electronegativity (Pauling Scale) 2.55: Electron affinity: 194.959 kJ/mol
In this effort, he built on the earlier work of many other chemists, notably Antoine Lavoisier (1743-1794), Humphry Davy (1778-1829), John Dalton (1766-1844) and Jacob Berzelius (1779-1848). The table revealed regularity in the properties of the elements, so it’s now known as the Periodic Table. Start studying Periodic Table Scientists.
