When did modern chemistry start?

Modern chemistry is generally considered to have started in the 18th century, specifically with the publication of Antoine Lavoisier's book "Elements of Chemistry" in 1789. Lavoisier is often referred to as the "father of modern chemistry" due to his crucial contributions in defining chemical elements and introducing the concept of chemical reactions. His work laid the foundation for the development of modern chemical principles and theories.

Modern chemistry is generally considered to have started in the late 17th century, with the development of the scientific method and the emergence of notable chemists such as Robert Boyle. However, the field of chemistry has evolved over time, and various key discoveries and advancements have contributed to its modern understanding and practices.
