Periodic Table Artifacts

The artifact that I have chosen to include on the Golden Record is the Periodic Table of the Elements. I have chosen to include the Periodic Table on the Golden Record because the table can be used to predict properties of elements, even the elements that have not been discovered. I find it fascinating that the Periodic Table can discover new elements and it organizes a ton of information about elements. The elements on the left are metals and the elements on the right are nonmetals which are shown how they are related to one another by columns, which are the groups, and the rows, which are the periods. The periods and groups indicate how the elements have similar characteristics and is arranged by their atomic number, chemical properties,

The table is very useful for students and scientists because it helps predict the types of chemical reactions and looking at the table tells you a lot about whether it conduct electricity, whether the element is hard or soft, and many other characteristics. The periodic table is one of the most important tools in chemistry history. It describes the atomic properties like the atomic mass, atomic number, and the relationships between the elements. The elements are arranged by groups and periods. The elements are group in particular groups and periods because it lets me know if the element has similar or different characteristics than another element. The periodic table describes every element known to man which is incredible because it tells us which element is dangerous. Each element has its own data which is the atomic mass and atomic number. If a person does not know which element he is holding, he can use the atomic number and the atomic mass to identify the substance. The element also has information that let a person know how the element will react. However, if a new element is discovered the new element can be compared to the other elements on the periodic table to see if it is similar to all the other

He was born on February 8, 1834 and died on February 2, 1907 in Saint Petersburg, Russian Empire. Dmitri Mendeleev was the youngest out of 17 siblings. Before he created the Periodic Table, he was a school principal and a teacher, and his mother encouraged him to patiently search for the divine and the scientific truth. His mother took him across Russia to get him a better education which the University in Moscow did not accept him. In the late 1860s, Dmitri published his very first textbook which was title Organic Chemistry and eventually was rewarded with an award from Petersburg Academy of Sciences. In the early 1900s, Mendeleev died at the age of 72 in Russian Empire at Saint Petersburg from influenza. The radioactive element number 101 mendelevium was named after him. There were approximately 56 known elements, and there was a new element discovered every year. Mendeleev worked on the periodic table for a while as he was teaching. He wrote a new textbook, Principles of Chemistry, and after a while he had discovered new patterns that led him to the periodic table. One of his popular quotes that got my attention, and that I was amazed by was when he said “I saw in a dream a table where all elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper, only in one place did a correction later seem necessary.” Later Mendeleev did a presentation and title the periodic table
