The periodic table shows the classification of elements. It shows the elements’ atomic numbers, masses, and symbols for each element. Elements are placed into rows and columns. The rows are called periods, and the columns are called groups. These help classify where the elements go on the periodic table. For example, the elements in the very last group on the periodic table are known as inert and noble gases. The modern periodic table resulted from trial, error, and succession. As more elements were discovered, the periodic table had to go through many changes to fit these newly discovered elements. This led to the modern periodic table we have today. Back in EBC, there was little if any science that was known. Although Gold (Au), Silver (Ag), Tin (Sn), Copper (Cu), Lead (Pb), and Mercury (Hg) are used on the modern periodic table, these elements were known by people for thousands of years. Aristotle, a philosopher, thought that the world was not just created out of nowhere. It has to be created by something. Aristotle thought that “roots” created the Earth. Plato, another philosopher, agreed with Aristotle. However, Plato called the “roots” “elements” instead. The term element was originally associated with what created the Earth: Air, Earth, Water, and Fire. These “elements” were used to explain what made up the Earth. People agreed with this idea for over a thousand years, until modern elements were discovered starting in the 1600s (WOU). In 1649, there
