About the Periodic Table
How to use
Click any element to see its properties. Use the search bar to find elements by name, symbol, or atomic number. Filter by category using the coloured chips above the table.
Element Categories
118 elements are classified into 10 categories: alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides, and actinides.
Periods & Groups
Rows are called periods (1–7). Columns are called groups (1–18). Elements in the same group share similar chemical properties. Period determines the number of electron shells.
f-block Elements
Lanthanides (La–Lu, Z=57–71) and actinides (Ac–Lr, Z=89–103) are the f-block elements. They are placed separately below the main table for layout reasons. All actinides above Uranium (Z=92) are synthetic.
What is Interactive Periodic Table?
The interactive periodic table is an educational reference tool that presents all 118 confirmed chemical elements in the classic tabular layout first proposed by Dmitri Mendeleev in 1869. Each element tile shows its atomic number, chemical symbol, name, and standard atomic weight at a glance. Clicking any element opens a detailed data panel covering its full physical and chemical profile.
The property data for each element includes atomic number, atomic mass, electron configuration, electronegativity (Pauling scale), melting point, boiling point, density at standard conditions, discovered year and discoverer, and a short description of its main industrial and scientific uses. Elements are color-coded by category — alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides, and actinides — so you can immediately spot group relationships and periodic trends.
This tool is designed for students studying chemistry at GCSE, A-level, or undergraduate level, as well as professionals who need quick property lookups without navigating textbooks or Wikipedia. Filters let you highlight elements by category, state of matter at room temperature, or block (s, p, d, f), making it easy to see periodic trends like increasing atomic radius or decreasing ionisation energy across periods. All data is sourced from IUPAC recommendations and the NIST Chemistry WebBook.
How to Use Interactive Periodic Table

Use the detailed panel for homework, exam revision, or professional property lookups.
Key Benefits
Atomic mass, electron configuration, melting point, boiling point, density, electronegativity and more.
Ten element categories are color-coded so group patterns and periodic trends stand out immediately.
Filter by category, block, or physical state to focus on the subset of elements you are studying.
Find any element in seconds by typing its name, symbol, or atomic number into the search bar.
Frequently Asked Questions
There are 118 confirmed elements. Elements 1-94 occur in nature; elements 95-118 are synthetic, produced in nuclear reactors or particle accelerators.
An electron configuration describes how electrons are distributed among orbitals in an atom. For example, carbon is 1s2 2s2 2p2, meaning it has 2 electrons in the 1s orbital, 2 in 2s, and 2 in 2p.
Atomic masses are taken from the IUPAC 2021 Table of Standard Atomic Weights, which represents the most up-to-date internationally accepted values.
Placing all 14 lanthanides and 14 actinides in the main table body would make it too wide to print on a standard page. The separate rows are a convention established in the mid-20th century.
