حول الجدول الدوري
The GuruAlpha Periodic Table is an interactive reference for all 118 chemical elements. Click any element to see its properties, electron configuration, common uses and discovery information. The table is color-coded by element category and supports searching by name, symbol or atomic number.
The periodic table is the fundamental organizing framework of chemistry. Dmitri Mendeleev created the first version in 1869, arranging elements by atomic weight and noticing periodic patterns in their properties. The modern table arranges elements by atomic number, revealing the periodic law: elements with similar electron configurations exhibit similar chemical properties.
The interactive design lets you explore the table at your own pace. Hover over any element to see a quick preview of its key properties. Click for the full profile: atomic number, symbol, name, atomic mass, category (metal, nonmetal, metalloid), electron configuration, electronegativity, density, melting/boiling points, discovery year and common uses.
The color coding groups elements by category: alkali metals (red), alkaline earth metals (orange), transition metals (yellow), post-transition metals (green), metalloids (teal), nonmetals (blue), halogens (purple), noble gases (pink), lanthanides (light green) and actinides (light yellow). This visual grouping makes it easy to identify elements in the same family.
The search feature finds elements by name, symbol or atomic number. The filter lets you view only specific categories, which is useful for focused study. The comparison tool lets you select two elements and compare their properties side by side.

الأسئلة الشائعة حول الجدول الدوري
How many elements are there?
118 confirmed elements, from Hydrogen (1) to Oganesson (118). Elements 1-94 occur naturally; 95-118 are synthetic.
What is electron configuration?
The arrangement of electrons in an element's energy levels. It determines the element's chemical properties and position in the periodic table.
What is electronegativity?
A measure of an atom's ability to attract bonding electrons. Fluorine (3.98) is the most electronegative element.
Can I compare elements?
Yes. Select two elements to see their properties compared side by side, including atomic mass, density and electron configuration.
