: The tendency of an atom to attract electrons increases as you move toward the top right (excluding noble gases).

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

: The energy required to remove an electron increases as you move toward the top right. Chemical Bonding : The tendency of an atom to attract

: Occupying most of the left and center of the table, metals (like Gold or Iron) are typically shiny, conductive, and tend to lose electrons in reactions. : One atom "steals" electrons from another (e

: One atom "steals" electrons from another (e.g., Sodium and Chlorine forming Salt).

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
