About this tool
This interactive periodic table lays out all 118 elements in the familiar grid, and tapping any cell opens its key facts β name, symbol, atomic number and atomic mass. Color coding by family makes it easy to spot metals, nonmetals, noble gases and the other groups at a glance. The whole table is bundled with the page and runs in your browser, so it works without sending anything to a server.
Frequently asked questions
What information does each element show?
Each cell shows the element symbol, its atomic number (the count of protons, which fixes its place in the table) and its standard atomic mass. Selecting an element opens its full details, including its name, which is handy for homework, lab work or a quick chemistry refresher.
How is the periodic table organized?
Elements are arranged by increasing atomic number, left to right and top to bottom. The vertical columns are groups, whose elements share similar chemical behavior, and the horizontal rows are periods; this tool colors the families so trends like the noble gases on the far right are easy to follow.
Does this work offline, or is data fetched from a server?
All the element data ships with the page, so the table runs entirely in your browser and keeps working even offline. Nothing you tap or search is sent to a server.
