Chemistry Of | The Elements

As you move across or down the table, specific chemical behaviors follow predictable patterns known as periodic trends:

Elements are categorized into groups (columns) and periods (rows) that share similar characteristics: Chemistry Of The Elements

: One atom "steals" electrons from another (e.g., Sodium and Chlorine forming Salt). As you move across or down the table,

: The size of an atom generally increases as you move down a group and decreases as you move left to right across a period. These elements are organized in the Periodic Table

The chemistry of the elements is the study of the 118 identified chemical substances that make up all matter in the universe. These elements are organized in the Periodic Table based on their atomic number, electron configurations, and recurring chemical properties. Licensed by Google The Architecture of Elements

Each element is defined by its , which is the number of protons in its nucleus. This fundamental value determines the element's identity and its position in the periodic table. The chemistry of an element is primarily driven by its valence electrons —the electrons in the outermost shell—which dictate how it bonds with other atoms. Major Groups and Trends

: Atoms share pairs of electrons to achieve stability (e.g., Oxygen and Hydrogen forming Water).
