1.8.A—Explain the relationship between trends in the reactivity of elements and periodicity

Explain the relationship between trends in the reactivity of elements and periodicity.

• The likelihood that two elements will form a chemical bond is determined by the interactions between the valence electrons and nuclei of elements.
• Elements in the same column of the periodic table tend to form analogous compounds.
• Typical charges of atoms in ionic compounds are governed by the number of valence electrons and predicted by their location on the periodic table.
