A snapshot of the periodic table.
Everything you need to know about the periodic table.
The periodic table contains 118 confirmed elements. Of these, 94 occur naturally on Earth, while the remaining 24 are synthetic elements created in laboratories through nuclear reactions.
Click any element to reveal its atomic number, symbol, atomic mass, category, state at room temperature, melting point, boiling point, density, electron configuration, group, period, block, and year of discovery.
Elements are arranged in order of increasing atomic number across 7 periods (rows) and 18 groups (columns). Elements in the same group share similar chemical properties. The table is divided into s-block, p-block, d-block, and f-block elements.
Elements are classified into 10 categories: alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides, and actinides. Use the filter buttons to highlight each group.
Tungsten (W, atomic number 74) has the highest melting point of all elements at 3422°C, making it essential for high-temperature applications such as light bulb filaments and rocket nozzles.
Uranium (U, atomic number 92) is the heaviest naturally occurring element with an atomic mass of 238.029 u. Elements with atomic numbers above 94 are entirely synthetic.
This free interactive periodic table of elements covers all 118 chemical elements — from Hydrogen (H, atomic number 1) to Oganesson (Og, atomic number 118). Each element card displays the atomic number, chemical symbol, element name, and atomic mass. Clicking an element opens a detailed panel showing its electron configuration, melting point, boiling point, density, state at room temperature, and year of discovery.
Elements are colour-coded by category: alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides, and actinides. Use the search box to find any element by name, symbol, or atomic number, or use the filter buttons to highlight a specific category.
The periodic table was first published by Dmitri Mendeleev in 1869. Today it is the most important reference tool in chemistry, physics, and materials science. Whether you are a student looking for a periodic table for studying, a teacher preparing chemistry lessons, or simply curious about the elements, this tool provides accurate, up-to-date data for every element.
