The Periodic table
The periodic table is a very useful tool that was thought of in the 1700’s. It was first brought up by the questions chemist could not solve, such as “when will we know when have found all the elements”. This was the beginning of the periodic table. By the year 1700’s there was only 13 elements discovered a few of those elements actually included copper, silver, and gold. Chemists began to wonder if there was other elements not known of. As time moved on chemist began to find more elements, they used scientific methods to find these elements. Sooner or later chemists wanted a solution to the questions that had been beckoning them from the start. To begin to answer these questions chemist needed to find a logical way to recognize …show more content…

Doberier (1780-1849) published a classification system. In the system he created, the elements known were grouped into triads. He began to place all these elements by similar properties. Dmitri Mendeleev’s a Russian chemist and teacher, also played a big role in the creation of our now periodic table. Mendeleev in 1869 created a table of elements, and later that year another German chemist, Lothar Meyer, published a very similar table; fortunately Mendeleev was given more credit, for he had it done first and was better at proving his point about the periodic table.
Mendeleev later found himself working on a textbook for his students; Mendeleev goal was to demonstrate the relationship of 60 different elements. He began by writing down all the physical and chemical properties of each element on a note card and moved them around until he found an order that worked. Mendeleev arranged the elements in his periodic table in order of increasing atomic mass (chemistry book).
The Periodic table as you can see has been around for quite some time but do you really understand the components of a periodic table? The periodic table is composed of rows and columns called groups and periods, the groups move from side to side in a horizontal manner and the electrons on the same group have the same number of electrons in the outer
