The periodic table flashcards on this page are designed to help you learn this important information, or to create your own oversized periodic table for use as a reference. These are usually part of important safety or warning information. Additionally, some product labels will contain chemical element symbols. For example, medical laboratory tests will use labels that are much easier to interpret with a basic knowledge of element symbols like Na, Cl, HCO 3, and O 2. Knowing element symbols and their corresponding names is essential in many STEM careers. Outside the classroom having a knowledge of the periodical table, chemical elements, and their properties can be quite useful. Learning various properties of these elements is often a requirement of science classes and allows chemistry problems to be solved in less time. We created a timeline of the history of the periodic table.The Periodic Table of Elements organizes all the known elements that make up the chemical matter around us. The Periodic Table has constantly been improved and developed over the past 200 years, but in 1869 Dimitri Mendeleev finished the first version of the periodic table as we know it today, by arranging the elements by atomic mass and leaving spaces open for the elements that were not yet discovered. Who invented the Periodic Table of Elements? The periodic table also gives us an idea of what the characteristics of an element might be and help us predict how an element might react based on in which group it is located. The Periodic Table of Elements can be used as an assisting tool in chemical calculations, when a specification of an element is needed it is easily found in the Periodic Table. How is the Periodic Table of Elements used? The table lists all the elements that are currently known (118), in descending order of the number of protons that are present, in a single atom of the element. The Periodic table of elements is a tool, developed by scientists over hundreds of years. List of all the elements and their properties:
