If you’re looking for a free printable version of the periodic table, this free Excel template can help. By having your own copy of the periodic table of elements on hand, you can reference it anytime you need. That’s why a printable periodic table is a necessary tool.
Many people never memorize the entire table. Memorizing all of the 118 elements is a difficult task. There are 18, and all the elements in a group have similar chemical properties. A period is a horizontal row there are seven on the periodic table.Ī group, or family, is a vertical column. To help organize the elements, the modern periodic table is divided into periods and groups. Today, the periodic table has 118 different elements, and has undergone extensive changes since Mendeleev’s first version. And as these elements were found, the periodic table expanded. Mendeleev’s original table was incomplete, but was such a powerful scientific tool that it was able to predict the weights and other properties of yet-to-be discovered elements. As early as 1869, Russian chemist Dimitri Mendeleev began arranging the then-known elements by atomic weight, creating what we now call the periodic table. By 1809, at least 47 were known, and by the mid-1800’s, naturalists were attempting to organize them.

To summarise, the periodic table is useful as it is arranged in one easy-to-use guide to provide a lot of details about elements and how they relate to each other. Order correlates usually with increased atomic mass. As the atomic number increases, the elements are distributed from left to right and top to bottom. The periodic table of elements arranges in a detailed collection of all known chemical elements. The atomic number of the element is the number of protons in the nucleus of the element. The periodic table is a tabular array of chemical elements organized by atomic number, from the lowest atomic number element, hydrogen, to the highest atomic number element, oganesson.
