Periodic trends describe patterns in properties across periods and groups. For instance, atomic radius generally decreases from left to right within a period due to increasing nuclear charge, while it increases down a group. Ionization energy and electronegativity typically increase across a period and decrease down a group. These trends help predict how elements will bond and react, guiding chemists in selecting materials for specific applications.
