What Are Periodic Trends?
Definition and Significance
Periodic trends refer to the pattern of variation in certain properties of elements as you move across a period or down a group in the periodic table. These trends are fundamental in predicting the behavior of elements in chemical reactions, bonding, and other chemical properties. Understanding these trends allows students to anticipate how elements will interact, which is critical in fields ranging from materials science to biochemistry.

Common Questions Covered in the Gizmo Answer Key
- How does atomic radius change across a period?
Explanation: Atomic radius decreases across a period due to increasing nuclear charge pulling electrons closer to the nucleus. - Why does ionization energy increase up a group?
Explanation: Because electrons are closer to the nucleus and more tightly held, making it harder to remove an electron as you move up a group. - What is electronegativity, and how does it vary across the periodic table?
Explanation: Electronegativity measures an atom's ability to attract electrons. It increases across a period and decreases down a group. - How do metallic properties change down a group?
Explanation: Metallic character increases down a group due to larger atomic sizes and weaker hold on valence electrons. - Explain the trend of electron affinity across a period.
Explanation: Electron affinity generally becomes more negative across a period as atoms more readily accept electrons.
