: The tendency of an atom to attract electrons increases as you move toward the top right (excluding noble gases).
: Found on the upper right side, nonmetals (like Oxygen or Nitrogen) are often gases or brittle solids and tend to gain or share electrons.
: Located in Group 18, these elements are highly stable and rarely react with others because they have a full set of valence electrons. Periodic Trends Chemistry Of The Elements
: Atoms share pairs of electrons to achieve stability (e.g., Oxygen and Hydrogen forming Water).
: Electrons flow freely among a lattice of metal atoms, giving metals their unique strength and conductivity. : The tendency of an atom to attract
Elements are categorized into groups (columns) and periods (rows) that share similar characteristics:
: The size of an atom generally increases as you move down a group and decreases as you move left to right across a period. Periodic Trends : Atoms share pairs of electrons
: 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.
