history of the perodic table

           The hitsroy of the periodic table was a long process that consisted of seven scientists. First it started with Dalton who was very intrested with the weather. he was very intelegent and he was teaching school at age 12.  Dalton came up with that each element had it own building blocks witch are called atoms. the second scientist was Bezalius, he came up with his own chemistry equipment and he discoverd the atomic weights of 45 of the elements in the perodic table. He is the scientist that found sicilon. the third scientis is Doberiner, he founded all of the family/element groups in the perodic table. he also came up with the triads; sodium, potassium, and lithium. the fourth scientist is Mendeleev, he was a very smarth young man and becuase of his mother seeing this he got a education he he helped the scientfic world. Mendeleev came up with the perodic table and the way that it was set up. he did this by writing all of the elemts with it atomic weight on cards and he started organizing the firts 65 elements. The fifth scientist is Cannizaro, he said that the number of gasses is equal to the number of solids. People accually started to belive him becuase he found the atomic weights of 65 elements and he came so close the the atomic weight that we know now. The sixth scientist is Newlands, he said that the elements are arranged by weight and he said that they are like octives on a panio every eighth note it starts over again. no one belive him when he told the scientist in the world they though that he was carazy saying that once he figured it out to get the elements to play him a song. the seventh and final scientist is Mosley and his contrubution to the perodic table is he organized the perodict table by the atomic number.

option two:
      Mendeleevs mother died when he arived in moscow after his mothers facotry burnt down. The trip to moscow tired her out and she had done what she set out to do. To get her son an education. His mothers death was probally the most horible thing that had ever happened to him, and he would strive on doing what her dream was, this was for him to have and education and thats probally why he did all of the great things that he did was so he would fofill his mothers dreams, and not let her down.
