Although people still did not understand the way of elements they were still brought up and used. ]]> 2019-02-22 13:19:19 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334109700 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334109898 During Ancient Times the known elements to the periodic table was Copper, Silver, Sulfur, Tin, Gold, Lead, Mercury, Carbon, and Iron. As time passed more and more elements were found. ]]> 2019-02-22 13:19:58 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334109898 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334112461 The new element "Phosphorus", Henning Brand had created this element by concentrating urine. ]]> 2019-02-22 13:27:55 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334112461 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334113374 This was the first turning point in the periodic table. "Lavoisier’s 1789 Table of Simple Substances" was brought and it was the new thing for that era, so many more elements such as bringing Light and Heat into it, Oxygen, Nitrogen, Hydrogen, Carbon, Chlorine, Fluorine, Boron, Cobalt, Manganese, Molybdenum, Nickle, Platinum, Tungsten, ]]> 2019-02-22 13:30:12 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334113374 https://padlet.com/jb220345/uwmxx434a1zv/wish/334599016 Still during this year the elements were re organized by categories, separating the metals and non-metals. Not being the best idea for the periodic table it was what they thought was best. ]]> 2019-02-24 17:58:30 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334599016 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334599754 Introducing the new method of the periodic table called "Lothar Meyer’s 1864 periodic system" elements were organized by the weight and density of each element. Also new elements were discovered. ]]> 2019-02-24 18:03:23 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334599754 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334600574 Dmitri had discovered many new elements in the Periodic Table, many of which he had predicted of specific elements. ]]> 2019-02-24 18:09:22 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334600574 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334600926 This is when gases were finally discovered. William had put them into the Periodic Table making them elements of which consisted of a whole new column in the table. ]]> 2019-02-24 18:12:24 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334600926 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334601454 This was when the discovery of "protons" happened. Elements were put into the periodic table based on their atomic number aka number of protons rather than putting them by there atomic weight. Each element was now being identified more and more. The Periodic table was now called "Deming's 1925 periodic table", more recognition to the table was known.]]> 2019-02-24 18:16:32 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334601454 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334602183 Elements were now looking more like they do know in the periodic table, discovering how to organize these elements of "unstable actinide" elements this started them to place them in their own row below the rare-earth elements. Element 101 was discovered in 1955. ]]> 2019-02-24 18:23:00 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334602183 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334602882 In today's Periodic table more elements have been discovered, elements have also been reorganized.  Elements are arranged from left to right and top to bottom in order of increasing atomic number.
The rows are called periods. The period number of an element signifies the highest energy level an electron in that element occupies.
The table is consisted by Atomic number, Atomic symbol, Atomic weight. ]]> 2019-02-24 18:27:03 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334602882 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/334603928 In this lessons based on the History of the Period Table. The Periodic table has been here for a long time. Since the Ancient Times when basic elements were known. As time passed by new elements were discovered and put into the table as being part of it, Elements were still not well known but the idea of it was there. Though out the years many scientists have tried to find many ways to organized and discover the elements, it has taken many years and errors for them to fully understand it, even today elements are still being discovered and added to the Periodic Table. It is amazing to know how far this table has gone, just starting with basics of 9 elements to having 118 elements, that is discovering 109 elements though the years. ]]> 2019-02-24 18:34:30 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/334603928 jb220345 https://padlet.com/jb220345/uwmxx434a1zv/wish/335337154 2019-02-26 13:32:35 UTC https://padlet.com/jb220345/uwmxx434a1zv/wish/335337154
