Periodic Trends

Periodicity Repeating (periodic) patterns of physical and chemical properties among elements that define families with similar properties. The periodic table displays this repeating pattern, which is related to an atom’s outermost electrons. Explain the relationship of an elements position on the periodic table to its atomic number. Use the periodic table to identify the three classes of elements: metals, nonmetals, and metalloids. Relate the position of an element on the periodic table to its electron configuration and compare its reactivity with other elements on the table. Identify trends on the periodic table (ionization energy, electronegativity, and relative size of atoms and ions.)
