Since ancient times, some elements like carbon, copper, silver, gold, iron, mercury, lead, and tin was known to Indians, Egyptians, Romans, Chinese and Greeks as people used to use these elements already. Among these, the first element to be discovered is considered to be copper. In ancient times, charcoal was widely used in the day-to-day lives of people and it was used to reduce zinc, copper, and tin from their respective ores.
After ancient age, came the time of Alchemists i.e., from 1 A.D. to 1735. Magnus discovered arsenic in 1250. Nicolas Lémery discovered antimony in 1707. Henning Brand, a German scientist discovered phosphorus in 1669. Naturally occurring phosphorus exists as P4 in two forms: red and white phosphorus. White phosphorus is toxic while red phosphorus is used in safety matchsticks.

Henri Moissan got the Nobel Prize in chemistry in 1906. Gallium was discovered by Boisbaudran in 1875. Spectroscopy was used to discover many of the so-called rare earth metals which actually exist in high concentration in the Earth’s crust. Since these metals are difficult to mine therefore were difficult to be discovered. These metals have a large number of applications. For example, neodymium and samarium are powerful magnets, so are used in electrons and yttrium is used in microwave resonators. Ytterbium was discovered by Marignac in 1878. In 1879, samarium was discovered by Boisbaudran. In 1878, scandium was discovered by Nilson and holmium was discovered by Delafontaine. Thulium was discovered by Cleve in 1879.

Germanium was discovered by Winkler in 1886. Argon by discovered by Rayleigh & Ramsay in 1894. Helium was discovered by Ramsay in 1895. The noble gases krypton, neon and xenon were discovered by Ramsay and Travers in 1898. Some elements such as radium and polonium were discovered by the natural radioactive decay of some radioactive elements in 1898. Becquerel, Pierre and Marie Curie got the Noble Price in Physics in 1903 for explaining radioactivity phenomenon.
