What is the periodic table for? Where is it used?

The periodic table is a reference material, the result of many years of work. It is used in the study of inorganic chemistry. Each element in the table has its own serial number, it also shows the charge of the atomic nucleus. Knowing this, you can find out how many protons and electrons are contained in an atom, which means we can find out the number of neurons. The table shows the atomic masses of all elements. Thus, even with a cursory glance, we can learn a lot about an element using a table, including the atomic structure of a particular element.
