The Periodic Table is organized by atomic structure and groups, and includes information on atomic number and the number of protons in an atom’s nucleus. Click on a group along the top of the tool, and all elements in that group will become highlighted.
Click or tap an element to reveal a visual of the atom and the outer electron shell as well as links to a wiki page.
The drop down menus provide information on reactions, compounds, state, structure, colour, melting point, boiling point, period, and group.
