Which chemist is considered the Father of Modern Chemistry and helped construct the metric system, published the first list of elements, and named oxygen and hydrogen?

• A. Antoine Lavoisier
• B. Louis Pasteur
• C. Justus Freiherr von Liebig
• D. Antoine-Alexis Cadet de Vaux

Answer: (A)

Antoine Lavoisier is celebrated as the father of modern chemistry because he transformed the field into a precise, measurement-driven science. He insisted on careful experimentation and quantitative data, which led to the law of conservation of mass and a shift away from the alchemical notion of combustion. He demonstrated that combustion involves the reaction with the element oxygen, and it was he who named oxygen and hydrogen, providing a clear vocabulary for chemical substances. He published treatises that contained the first widely recognized list of elements and laid the groundwork for standardized chemical nomenclature. He also played a significant role in promoting the metric system in France, aligning chemical measurements with a universal, decimal-based framework. This combination of theoretical reform, systematic naming, and standardized measurement marks him out as the key figure referenced. Other options—Pasteur in microbiology, Liebig in organic and agricultural chemistry, or Cadet de Vaux who isn’t as central to these foundational developments—don’t align with these specific contributions.
