History
History |
The element Oxygen was discovered by Carl Wilhelm Scheele in year 1774 in Sweden and United Kingdom. Oxygen derived its name from from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming' |
The element Iron was discovered by unknown in year 2000 BC in unknown place. Iron derived its name derived its name from from English word (ferrum in Latin) |
