Há 2 dias · Chlorine dioxide (ClO 2 ), also known as chlorine peroxide and chlorine (IV) oxide, is a low-boiling red-brown liquid and yellow-green gas. It has an odd number of valence electrons, which makes it an unusual stable free radical and therefore paramagnetic. In 1811 or 1814 (accounts vary), pioneering English chemist Sir Humphry Davy discovered ...

Há 4 dias · Beddoes employed chemist and physicist Humphry Davy (1778–1829) as superintendent of the institute, and engineer James Watt (1736–1819) to help manufacture the gases. Other members of the Lunar Society such as Erasmus Darwin and Josiah Wedgwood were also actively involved with the institute.
Há 4 dias · Sir Humphry Davy’s experiments with electrolysis were key. He first named it “Alumium” and then changed it to “Aluminum” in 1812. However, British chemists chose “Aluminium” instead. They thought it matched better with other element names. This choice in the early 1800s caused the name to have different spellings today.
