![]() ![]() This was because he noticed a similarity in the atomic weight and physical properties of the chemicals in every 8 chemicals in his list. He proposed a law of octaves to separate and divide up the elements. This is something that would later be very important when the first proper periodic table was produced. He was the first chemist to take the list of known elements at that time and separate them into different groups. John Newlands was a very important figure in 19th century chemistry. It was the basis for our modern understanding of the elements. This book listed the basic elements, which were defined to be the smallest particles of matter that couldn't be subdivided any further. Antoine-Laurent de Lavoisier wrote the first modern textbook on chemistry in 1789. This was the first discovery of an element. Hennig Brand conducted experiments that led to his discovery of phosphorus in 1669. It's in the 17th and 18th centuries that we can start to see the origins of the periodic table, which is tied to the discovery of the first chemical elements. But they didn't do much to advance our understanding of matter that is something that would come later. Therefore, we can say that the ancient Greeks did understand the nature of elements and what they were in a basic way. ![]() In ancient Greece, Aristotle and Plato thought that everything on the planet came from four root sources. Going back to ancient times, we can see the roots of our understanding of the elements that make up the periodic table. There were many people who contributed to the ideas behind the periodic table, but some figures are credited more for its development than others. But who actually invented it? How did the periodic table evolve over the years? Why did the inventor of the table organize it in the way that we use it today? The development of the periodic table has a long history that involves many scientists over hundreds of years. The periodic table is central to the study of chemistry, and it's used to organize chemical elements in a coherent way. Who Invented the Periodic Table? Released - April 19, 2017 ![]()
