About this tool
Type an element name or chemical symbol and the explorer returns that element atomic number and category from a starter set of 30 common elements, from hydrogen through to lead. It is a quick reference for homework and revision, not a full 118-element table, and heavier or rarer elements outside the set will report no match.
Frequently asked questions
How many elements does this explorer cover?
A starter set of 30 common elements; rarer elements outside the set report no match rather than guessing.
Can I search by name as well as symbol?
Yes. Typing iron works just as well as typing Fe, and matching ignores upper and lower case.
