History
Name | Oxygen | Bromine |
History | The element Oxygen was discovered by W. Scheele in year 1771 in Sweden and United Kingdom. Oxygen derived its name from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'. | The element Bromine was discovered by J. Balard and C. Löwig in year 1825 in France. Bromine derived its name from the Greek bromos, meaning 'stench'. |
