About the Periodic Table
How to use
Click any element to see its properties. Use the search bar to find elements by name, symbol, or atomic number. Filter by category using the coloured chips above the table.
Element Categories
118 elements are classified into 10 categories: alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides, and actinides.
Periods & Groups
Rows are called periods (1–7). Columns are called groups (1–18). Elements in the same group share similar chemical properties. Period determines the number of electron shells.
f-block Elements
Lanthanides (La–Lu, Z=57–71) and actinides (Ac–Lr, Z=89–103) are the f-block elements. They are placed separately below the main table for layout reasons. All actinides above Uranium (Z=92) are synthetic.
