Periodic Trends: Electronegativity and Reactivity

Students will investigate the trends in electronegativity and reactivity, connecting them to an element's position on the periodic table.

Key Questions

  1. Analyze the relationship between an element's electronegativity and its tendency to form ionic or covalent bonds.
  2. Compare the reactivity of alkali metals with that of halogens, justifying the differences based on electron configuration.
  3. Predict how the electronegativity of an element will change as you move down a group.
