Explore the interactive periodic table — all 118 elements
Click any element to see its atomic number, atomic mass, symbol, electron configuration, group, period and classification. Elements are colour-coded by category — alkali metals, noble gases, halogens, transition metals, metalloids and more — so trends across the table are easy to spot at a glance.
Find an element fast
Look it up by symbol (Fe for iron, Na for sodium), by atomic number, or by category. Each element opens a detail view with its key properties and common uses — handy for chemistry homework, exam revision, or a quick reference at the lab bench.
Reading the table
- Groups (columns) share similar chemical behaviour and outer-shell electrons.
- Periods (rows) fill successive electron shells from left to right.
- Blocks (s, p, d, f) map to the orbital being filled.

Frequently asked questions
Common questions about the Interactive Periodic Table.
How many elements are in the periodic table?
There are 118 confirmed elements, from hydrogen (1) to oganesson (118).
What does each element show?
Click any element to see its atomic mass, electron configuration, classification (metal, nonmetal, metalloid) and common uses.
How is the periodic table organized?
Elements are arranged by increasing atomic number into periods (horizontal rows) and groups (vertical columns), so elements with similar properties line up.
What are groups and periods?
Groups are the columns — elements in the same group share similar chemical behaviour. Periods are the rows, and correspond to the number of electron shells.
What’s the difference between metals, nonmetals and metalloids?
Metals conduct heat and electricity and are usually shiny and malleable; nonmetals generally don’t; metalloids (like silicon) sit in between and behave as semiconductors.
