However, the modern periodic table arranges them by atomic number, from lowest to highest.]]> 2021-12-15 19:39:50 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950295759 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950300484 In 1863, there were only 56 known elements and a new one was discovered about once every year.]]> 2021-12-15 19:42:35 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950300484 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950302056 Organizing the elements by their atomic number rather than their atomic weight did not change the arrangement of the periodic table.]]> 2021-12-15 19:43:31 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950302056 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950307725 Mendeleev’s Periodic table was the gaps he left, in these places he not only predicted there were as-yet-undiscovered elements, but he predicted their atomic weights and their characteristics]]> 2021-12-15 19:46:54 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950307725 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950309085 The columns in the table are used to separate groups of elements. The elements in a group often have similar properties and often have the same arrangement of outer electrons]]> 2021-12-15 19:47:45 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950309085 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950309878 Since Mendeleev’s table was introduced, there have been an estimated 700 alternate versions of the periodic table. Some of these were circular, triangular, or pyramid shaped]]> 2021-12-15 19:48:16 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950309878 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950315509 2021-12-15 19:51:34 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1950315509 How is this project topic relevant today? 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1952528627 It's relevant today because Mendeleev's history has lasted to today.]]> 2021-12-16 19:42:56 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1952528627 What did you know about your topic prior to the research project, and what new information have you learned during the research part of the assignment? 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1952533264 Me and Taty only knew that Mendeleev made the periodic table, but we learned that in 1863, there were 56 known elements and a new one was discovered every year.]]> 2021-12-16 19:46:14 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1952533264 How have you grown in science this year thus far? 7825121 https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1952538548 I understand the basic science and know about Molecules and atoms now.

I've learned a lot about physical and chemical changes :) (Taty)]]> 2021-12-16 19:49:54 UTC https://padlet.com/7825121/z6gkz7rq6atp0tiv/wish/1952538548
