How to use Periodic Table edit

Follow these steps to use the tool:

  1. Browse the table

    All 118 elements are displayed in the standard periodic table layout with colour coding by category.

  2. Filter by category

    Click any filter button to highlight a specific element group like noble gases, transition metals, etc.

  3. Click any element

    Click an element cell to open a detailed info panel with atomic mass, melting/boiling point, density and a full description.

  4. Explore properties

    Compare elements, discover interesting facts, and learn about electron configurations.

Frequently asked questions edit

There are 118 confirmed elements, from Hydrogen (1) to Oganesson (118). Elements 1–94 occur naturally; elements 95–118 are synthetic.
Elements are grouped into: alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, reactive nonmetals, halogens, noble gases, lanthanides, and actinides.
The electron configuration shows how electrons are distributed in orbital shells around the nucleus. For example, [He] 2s² 2p⁶ means 2 electrons in s-orbital and 6 in p-orbital of the second shell, on top of the helium core.
Lanthanides (elements 57–71) and actinides (89–103) are placed in separate rows at the bottom to keep the table compact. They form the f-block of the periodic table.
