Therefore, the atomic radius increases as the group and energy levels increase. - As you move across a period, the atomic radius decreases, that is, the atom is smaller. The outer electrons are closer to the nucleus and more strongly attracted to the center.
We were introduced to the terms atomic radius and ionization energy. We then graphed trends in atomic radius and ionization energy. We ended class with some guided notes on periodic trends in atomic radius, ionization energy, ionic size, Assignments: 1) Periodic Trend Graphing 2) Periodic Trends Notes (powerpoint)
HONORS CHEMISTRY. Chemistry: Principles and Reactions, revised 5th ed. Masterton & Hurley Brooks/Cole, 2006 / ISBN: 0-495-01140-1 This lesson is an introduction to periodic trends. It has students use the Science and Engineering Practice (SEP): Analyzing and interpreting data.Students work in groups to graph and analyze three periodic trends: atomic radius, ionization energy and electronegativity.
