The periodic table, also known as the periodic table of the elements is a tabular arrangement of chemical elements organized by their atomic number, electron configuration, and chemical properties. It provides a systematic way to understand and predict the behavior of elements. Elements in the same column, called groups, share similar properties, while elements in the same row, known as periods, have increasing atomic numbers. The table is a fundamental tool in chemistry, helping scientists classify and study the properties of over 100 different elements. The first periodic table to become generally accepted was that of the Russian chemist Dmitri Mendeleev in 1869. If you are excited to know more about the Periodic Table of Elements, then just take this quiz. So let's start it!
