Periodic Table Reference Tool
Browse all 118 chemical elements in an interactive, color-coded grid. Search by name, symbol, or atomic number, and click any element to see its full details.
How to Use the Periodic Table Reference Tool
- Scroll through the full grid of all 118 elements, color-coded by category.
- Type into the search box to filter by element name, symbol, or atomic number.
- Click any element tile to open a detail panel with its full name, symbol, atomic number, atomic mass, and category.
- Use the legend above the grid as a quick key to what each color represents.
Why Use This Tool?
Does this really include all 118 elements?
Yes — every element from Hydrogen (atomic number 1) through Oganesson (atomic number 118) is included, with its symbol, full name, standard atomic mass, and element category. This includes the synthetic, laboratory-made elements at the bottom of the table, not just the naturally occurring ones.
How are elements color-coded?
Elements are grouped into common chemistry categories — alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides, and actinides — each with its own color, shown in the legend above the grid. This makes it easy to spot patterns and groupings at a glance, the same way a printed periodic table poster would.
Can I search by atomic number instead of name?
Yes. The search box matches against the element's name, its one- or two-letter symbol, and its atomic number, so you can type "8", "O", or "Oxygen" and get the same result. This makes it quick to look up an element even if you only remember one piece of information about it.
Is this reference tool free for students and teachers?
Completely free, with no signup and no limits. It's built as a fast, distraction-free reference for chemistry students studying element properties, teachers pulling up quick facts during a lesson, or anyone curious about the building blocks of matter.
