How many elements are on the Periodic Table?

There are 118 confirmed elements on the Periodic Table, ranging from Hydrogen (atomic number 1) to Oganesson (atomic number 118). The tool displays all of them.

Can I search for an element by symbol or atomic number?

Yes. The search box accepts element names (e.g. Carbon), symbols (e.g. C), and atomic numbers (e.g. 6). Matching elements appear as clickable cards with full details.

What information is shown for each element?

Each element detail card shows the atomic number, symbol, name, atomic mass in atomic mass units, category, group, period, electron configuration, and the year it was discovered.

What do the colors mean?

Colors group elements by category: Alkali Metals, Alkaline Earth Metals, Transition Metals, Post-transition Metals, Metalloids, Nonmetals, Halogens, Noble Gases, Lanthanides, Actinides, and Unknown properties for the newest synthetic elements.

Is this Periodic Table up to date?

Yes. It includes all 118 elements through Oganesson, the most recently confirmed element. Synthetic elements with very short half-lives are included with their known or predicted properties.

What is Interactive Periodic Table of Elements?

The HIF Logic Interactive Periodic Table of Elements displays the full color-coded chart of all 118 known chemical elements — from Hydrogen (1) to Oganesson (118). Each element is grouped by category (Alkali Metal, Alkaline Earth, Transition Metal, Post-transition Metal, Metalloid, Nonmetal, Halogen, Noble Gas, Lanthanide, Actinide, and Unknown) and shown with its atomic number and symbol. Below the chart, a searchable element guide lets you look up any element by name, symbol, or atomic number to see its atomic mass, group, period, electron configuration, and year of discovery. It is a handy reference for students, teachers, hobbyists, and anyone curious about chemistry — no textbook or download required.
