periodic.lanl.gov
This is a good site. There are several others. Do a search for periodic table.

Answer 2

Fluorine was discovered by Karl Scheele in 1771, recognized as a halogen in 1825, and included in Mendeleev's periodic table of 1869. Fluorine is so active that it existed only in compounds and all efforts to isolate the element failed. Because of its high corrosiveness/toxticity, early fluorine chemists died from fluorine poisoning and the element was dubbed "Tiger of Chemistry." Fluorine, from Latin "fleure" meaning to flow, is the 13th most abundant element in the earth's crust and the most reactive of all elements--it even forms compounds with noble gases. Henri Moissan (1852-1907) In 1886, French chemist Henri Moissan attempted to isolate fluorine. Since platinum was one of the few substances that might resist fluorine, Moissan constructed equipment from this metal platinum and lowered the temperature (-50°C) to reduce fluorine's activity. Then he passed an electric current through a solution of potassium fluoride in hydrofluoric acid and achieved his goal--fluorine was finally isolated. In the electrolysis figure shown below, fluoride ions are oxidized at the positive electrode (anode) producing fluorine gas. Moissan made a full study of the properties of fluorine and its reactions with other elements. Shortly after receiving the 1906 Nobel prize in chemistry, Moissan suddenly died (fluorine poisoning?). Don't trust Wikipedia and don't get fluorine mixed up with fluoride.
