Periodic Table Explorer
100% PrivateEducation & Research ToolsExplore an interactive periodic table of all 118 elements, with filters and details.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
Click any element for its details.
No element selected yet. Click one in the table above, for example Fe (iron, number 26, standard atomic weight 55.845).
- 1Scan the table, or type a name, symbol or atomic number in the search box to highlight matches.
- 2Click a category button to dim everything except that family of elements; click it again to clear.
- 3Click an element to see its symbol, atomic number, standard atomic weight, category, group and period.
Search for "iron" or click cell 26. The detail card shows: symbol Fe, atomic number 26, standard atomic weight 55.845, category Transition metals, group 8, period 4.
- Weights are standard atomic weights (IUPAC conventional values at textbook rounding). For elements with no standard atomic weight, the bracketed value is the mass number of the most stable known isotope.
- Standard atomic weights are a snapshot: IUPAC revises a few values over time and some weights are published as intervals, so a current textbook may differ in the last decimal.
- Elements 109 to 118 are shown with "Unknown properties" because their chemistry has not been confirmed experimentally; their table positions are predictions.
- On narrow screens the table scrolls sideways so every cell stays readable and tappable.
Those elements have no stable natural form, so there is no standard atomic weight. The bracketed number is the mass number of the longest-lived known isotope, which is the convention chemistry tables use.
About this tool
The Periodic Table Explorer is a full interactive table of all 118 elements. Browse the grid, filter by category (alkali metals, halogens, noble gases and the rest), search by name, symbol or atomic number, and click any element for its detail card. It is built for quick lookups while doing homework, revising, or checking a value mid-experiment write-up.
