ELEMENTS

 (Regarded as the father of modern chemistry)

 He stated that Water, Air, Earth, Fire   decomposes, it consists of multiple elements! Not just single elements!

He also summarized a total of 33 elements

Air consists of Oxygen and Nitrogen!

If something such as Water can be separated by Physical methods, it should not be considered an element!

He also summarized a total of 33 elements

He also stated the elements cannot be further broken down.

He also classified the elements into gases, non-metals, metals, earths.

A lot of things (20 so called elements) that were considered by elements turned out not to be elements after his theory!

He arranged the elements systematically by arranging the elements according to ascending atomic number, he also grouped the elements with similar properties together, he also reserved empty spaces for elements not discovered yet.

He used X rays to find out the exact atomic numbers as well as the wavelengths of each element, then arranged the periodic table again according to the most updated information.

He laid the foundation of the periodic table we see now.
