paragraph 2- 1- The person that i found most interesting out of all the men we studied was Mendeleev. I think that he contributed to the periodic table more than anyone else because of how he classified the elements. Not only was able to arrange the elements on the table in a way that mad since but he left room for more elements. He was realistic about his beleifs about what elements might still be out there instead of just deciding that he had found them all.

Dalton set up a school to teach others and kept meteorological diary for 57 years. Dalton was an avid reader and a deep thinker. He said that an element is always the same weight by prper no matter where it was from. Dalton used his imagination as a microscope, and his theorys were dismissed. Bezalimus was one of the few people who agreed with the ideas of Dalton. He was a sweedish chemist who worked along side Dalton and he worked out the chemical formula notation. Some of Bezalimus's  acomplishments were  chemical notation, discovering new elements, and developing new chemistry terms such as catalysis, polymer, isomere, and allotrope. Dobereiner was responsible for the discovery of the elements chemical property. The way that he was able to figure this out was he picked out 3 elements with similar chemical propertys and evaluated them. Mendeleev was probly the greatest contributer to the periodic table, he organized all the known elements onto the periodic table and then he predicted many more that would be dicovered in later times. Connizaro measured atomic weights accuratly. He was a Russian Leonardo Divinci. John Newland contributed to the periodic table by arranging the elements by weight. Every 8 properties used to repeat.
