Key Concepts
Periodic Law
The properties of elements are periodic functions of their atomic numbers, repeating in regular patterns.
Periodic Trends
Predictable changes in element properties (like atomic radius and ionization energy) across periods and down groups.
Electron Configuration
The arrangement of electrons in atomic orbitals determines an element's position in the periodic table and its chemical properties.
Understanding Periodic Trends
The **Periodic Table** is organized by atomic number and group structure to reveal recurring patterns in chemical behavior. These patterns, known as **Periodic Trends**, are a direct consequence of the arrangement of electrons in atoms.
Key trends include **Atomic Radius** (which decreases across a period due to increasing effective nuclear charge), **Ionization Energy** (the energy required to remove an electron), and **Electronegativity** (the tendency of an atom to attract a shared pair of electrons).
Through this interactive periodic table, you can toggle between different property heatmaps to observe how period and group positions dictate an element's physical properties and chemical reactivity.
