Wrap up/Launch

 Periodic trends include atomic/ionic size, ionization energy, density, melting/boiling point, electronegativity and reactivity. Understand the concept that you are analyzing before explaining the trend.

Many factors that influence these trends such as electron shielding or repulsions, valence electrons, nuclear charge, intermolecular forces, energy levels, and pressure.
