Answer:
Their atomic theory of the elements
Step-by-step explanation:
The ancient Greeks believed that all matter consisted of four elements — earth, air, fire, and water
Everything on Earth consisted of these elements in different combinations.
Robert Boyle is best known for his famous Law — p₁V₁ = p₂V₂.
However, he was also an excellent chemist who did many experiments.
He found it was impossible to combine the four Greek elements into any substance.
Boyle found he could decompose many substances into simpler substances, but none of them was a Greek element.
He therefore rejected the Greek theory.
Almost 150 years before Dalton's atomic theory, Boyle proposed a new definition of an element:
An element is any substance that cannot be broken into a simpler substance.
