History

History
The element Arsenic was discovered by Bronze Age in year 1250 in unknown place. Arsenic derived its name from English word (Latin arsenicum)
The element Oxygen was discovered by Carl Wilhelm Scheele in year 1774 in Sweden and United Kingdom. Oxygen derived its name derived its name from from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'
