![]() ![]() First of all, you have to know what an atom is. The mass number is defined as the total number of protons and neutrons in an atom. In the periodic table, there is what is called a mass number. What is the mass number on the periodic table? But if you find a trick to learn it, it will be fun and easy. It will look difficult when you first see it. A periodic table is used to help provide information about an element while predicting it. Therefore the periodic table entered into the subject matter in school. Not only people who are experts in their fields, but also for ordinary people. The periodic table is of particular importance to people who study science. We created a timeline of the history of the periodic table.What is the importance 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. 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: ![]()
