Building on the work of alchemists, one significant transition to modern chemistry was a system of naming chemical compounds, first proposed in 1787 by Antoine Lavoisier and his colleagues. How do you think a system that is internationally accepted helps chemists in their work?

• It ensures clear, consistent communication of chemical names across languages and regions

• It encourages each lab to use unique local nicknames for chemicals

• It makes experimental procedures more secretive and harder to share

• It reduces the need to record safety information for substances
