History of the Periodic Table Austin Smith LSG5 Scientists all around the world have attempted to group, sort and organise elements together for hundreds of years, with initial classification systems dating decades before the dawn of an actual table in the nineteenth century. An example of early work prior to the 1800s is Antoine Lavoisier and partners Antoine Fourcroy, Louis-Bernard Guyton de Morveau and Claude-Louis Berthollet’s list of elements. While this one dimensional system documented all of the 33 elements known at the time (and still shares the same idea of organising the elements), sorting them based on a variety of physical factors proved to be much more complex than imagined (Scerri, 2011). Dobereiner’s Triads of Elements (Dobereiner’s Law of Triads, no date) In 1817, Johann Wolfgang Dobereiner was one of the first to create a milestone for future classification systems. He attempted to structure the elements together based off of elements with similar traits, grouping elements in groups of three, together forming what was called a ‘triad’ (Western Oregon University, 1997). Dobereiner created his three-element structure when he noticed that the atomic weight of strontium was almost the average of calcium and barium, all of which shared similar properties (Dobereiner’s Law of Triads, no date). Dobereiner noticed such pattens more often, two triads being the halogen triad, consisting of chlorine, bromine, and iodine as well as an alkali metal triad, consistingShow MoreRelatedHistory Of The Periodic Table1129 Words   |  5 PagesThe History of the Periodic Table Throughout history the periodic table of elements has been influenced and amended by multiple scientists.

With the works of these scientists, the periodic table was created as well as the periodic law. With this set, scientists as of today had been able to organize the elements without much trouble and were able to discover unknown elements. Although there are many elements in the world and many of them have not always been known of, the periodic table had been created to classify these elements as well as the tables corresponding patterns and trendsRead MoreHistory Of The Periodic Table Of Elements1664 Words   |  7 PagesLeonardo Miranda Mr. Tagami Chemistry 10/24/14 History of the Periodic Table of Elements The construction of the Periodic Table of Elements was prior to the discovery of the individual elements. Elements such as silver, gold, tin, copper, lead and mercury have been known for centuries. In 1649, the first scientific discovery of an element was made by Hennig Brand when he discovered phosphorous. Prior to Brand’s discovery, chemists had acquired an immense body of understanding concerning the propertiesRead MoreHistory And Development Of The Periodic Table2227 Words   |  9 Pages History and Development of the Periodic Table Ben Madden 10B â€Æ' Part A: Timeline of the Periodic Table 0 Ancient Greeks believed that everything was made of four elements mixed together in different proportions. These elements were fire, water, air and earth. 1661 Robert Boyle had an assumption that an element was an individual substance that could not be broken down further into a smaller substance through the process of a chemical reaction. Boyle’s assumption is considered to be theRead MorePart A HISTORY of the PERIODIC TABLE Antoine-Laurent Lavoisier discovered both hydrogen and600 Words   |  3 PagesPart A HISTORY of the PERIODIC TABLE Antoine-Laurent Lavoisier discovered both hydrogen and oxygen, although it is said that Henry Cavendish had earlier uncovered hydrogen. Lavoisier also helped create the metric systems (source 1). He wrote the first extensive list of elements containing 33 elements and distinguished metals and non-metals (source 5). Him and his area of work were particularly interested in compounds, element weight and chemical reaction (source 6).

It has evolved into a much easier piece of information to use because of all the many scientists and chemists that have revised it over the last hundred ish years. There are certain things on the periodic table that help to learn more about each element. Periodic families are used to help understandRead MoreThe Periodic Table Of Elements1123 Words   |  5 Pages Throughout history the periodic table of elements has been influenced and amended by multiple scientists.

Black established this was a form of air but also different from ‘common elastic air’. Therefore, he reasoned it must have been ‘fixed air’ and
