We created a timeline of the history of the periodic table. 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. Mendeleev’s Periodic Table was published in the German Journal of chemistry in 1869. Who invented the Periodic Table of Elements? Periodic Table of Elements (Interactive). NOTE: Nitrogen has the electron configuration of 2,5 and not 2,4 as stated in the game. Use the provided information about elements to determine their position in the periodic table. 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. An interactive game to help students learn and consolidate knowledge and understanding of the periodic table. 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.

As you can see in the periodic table shown in the figure below, the halogens include the elements fluorine (F), chlorine (Cl), bromine (Cl), iodine (I), and astatine (At). The latest release of the Periodic Table (dated ) includes the most recent abridged standard atomic weight values released by the IUPAC Commission on. It comprises 14 elements from the sixth period known as lanthanoids and 14 elements from the seventh period known as actinoids. 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. Every period can denote the energy levels and the number of shells present in an elements atom.The periodic table in its long form has a separate panel at the bottom. The Periodic table of elements is a tool, developed by scientists over hundreds of years. List of all the elements and their properties:
