In 1803 Dalton created "Dalton's Law" which was the first time anyone really compared the elements to one another. In 1828 Bezalius was the first to give the elements symbols and he was determined to weigh each atom of all the elements. Newlands started to arrange the elements by atomic weights and started to notice similarities between the multiples of 8 on the elements called the "law of octave". Mendeleev arranged the periodic table by comparing the similarities and the atomic mass. Moseley organized the periodic table by using atomic numbers.
Paragraph 2:
Option 1:
I find Mendeleev the most interesting because he was the man who put it all together. He wrote all the elements onto cards laid them out on a table and just looked at them for hours. But what made it even more difficult, like they said in the movie he was using a deck of cards with a lot of the cards missing. He was so determined to figure out the puzzle that he locked himself away and worked non-stop for three days. When he finally fell asleep he had a dream and solved the periodic table puzzle. I liked him the most because of his determination to finish what he started.
Good job, Hall Blake. Consider making your first paragraph more informative, but your second paragraph was well done. Consider a picture for your next post.
ReplyDeleteGreat super hero, hbbfootball22. It rocks. I really like how you gave us a history lesson for science class? yes i meant to put that question mark.
ReplyDeleteps i also found mendeleev to be the most interesting
