Periodic table
Also known as Mendeleev's periodic table, periodic table of chemical elements, periodic table of elements, the periodic table, periodic classification of elements
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). An icon of chemistry, the periodic table is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order of their atomic numbers an approximate recurrence of their properties is evident. The table is divided into four roughly rectangular areas called blocks. Elements in the same group tend to show similar chemical characteristics.
AI overview
The periodic table is an organized arrangement of all chemical elements into rows and columns that reveals a fundamental pattern: elements with similar properties repeat in a predictable way when ordered by their atomic numbers. It's a foundational tool used across chemistry, physics, and other sciences because it helps scientists understand and predict how elements behave and interact with one another.

Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3; it is usually shown at the foot of the table to save horizontal space.
