As the years went on more and more elements were discovered but even then, many of these new elements being discovered were not yet understood.]]> 2019-02-22 13:19:32 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/334109757 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/334111424 In 2019 it marks the 350th anniversary of Henning Brad. 350 years ago Henning Brand isolated phosphorus and he did this by concentrating urine. ]]> 2019-02-22 13:24:24 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/334111424 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/334112747 During this time many gases were being isolated such as Oxygen and Nitrogen . This is also the time when Antoine Lavoisier and L.B.G deMorveau made something called Table of Simple Substances. This would now be known as the Periodic table but back then it was only one column.]]> 2019-02-22 13:28:45 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/334112747 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/334114843 During the 1860s they started categorizing the elements by weight.]]> 2019-02-22 13:34:12 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/334114843 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/335117005 Mendeleev predicted that there would be missing elements on the Periodic system. He predicted that they would weight 45,68, and 70. He was then nicknamed the father of the periodic table because later elements gallium, scandium, and germanium were discovered with the masses that he predicted. ]]> 2019-02-25 21:44:18 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/335117005 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/335123828 William Ramsay discovered many noble gases. When he discovered them he made a proposal to Dmitri Mendeleev to add the noble gases as a column to the periodic table.]]> 2019-02-25 22:07:04 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/335123828 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/335308441 Since protons and elemental isotopes were discovered Henry wanted to rearrange the order of the periodic table. He decided to order it by periodic number not by weight.]]> 2019-02-26 12:05:33 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/335308441 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/335309233 The radioactive elements were a bit difficult because of their weight but Glenn Seaborg made them a new row to put them in. He would later be honored for this.]]> 2019-02-26 12:08:52 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/335309233 zophiag20 https://padlet.com/zophiag20/c8k54qctv287/wish/335309825 The periodic table we see now was settled in 2016.But now researchers are trying to push for an eight row to be added to the table. Now many scientist think that the table will need to be fixed later on because the tables periodically could break down due to the atoms getting bigger.]]> 2019-02-26 12:11:09 UTC https://padlet.com/zophiag20/c8k54qctv287/wish/335309825
