What this periodic table shows
This interactive periodic table displays all 118 known elements by atomic number, symbol, name, relative atomic mass, group, period, block, and chemistry category. It is built for quick chemistry revision, classroom reference, homework support, and fast comparisons between metals, non-metals, noble gases, lanthanoids, and actinoids.
Element categories explained
The color coding highlights major families of elements so you can compare reactivity, metallic character, and general properties at a glance.
Alkali metals
Group 1 metals are very reactive and usually form compounds with a +1 charge.
Alkaline earth metals
Group 2 metals are less reactive than alkali metals and commonly form +2 ions.
Transition metals
These d-block metals often show multiple oxidation states and are widely used in alloys and catalysts.
Post-transition metals
These softer metals sit between transition metals and metalloids and often have lower melting points.
Metalloids
Metalloids combine metallic and non-metallic properties, making them important in semiconductors and specialty materials.
Non-metals
Non-metals include many essential elements for life and often form covalent bonds in compounds.
Noble gases
These very unreactive gases have full outer electron shells and are used in lighting and inert environments.
Lanthanoids
The lanthanoid series contains rare-earth metals used in magnets, lasers, displays, and advanced electronics.
Actinoids
The actinoid series includes radioactive elements important in nuclear science, research, and energy applications.
How to use the periodic table
Start with an element's atomic number or symbol to find its position quickly. Then compare its group and period to spot patterns in valency, electron arrangement, reactivity, and physical properties. Click or tap any element to open a detail panel with classification, block, common uses, and a key chemistry fact for revision.
