Title: Summarize Periodic Trends
Description: Honors Chemistry
November 16, 2020

QUIZ:  Periodicity (10 points) - NOT given this year due to remote learning.

Review trends of periodic table.
     ...size of atoms (in periods and groups)
     ...ionization energies
     ...electronegativities
     ...metallic characteristics
     ...other trends (density, melting point)

Go over how elements got their names.

HW: Study for test on periodic trends.

TARGETS: Periodicity

Target 1: I understand how the periodic table is organized based on patterns.

Target 2: I can identify specific families and regions on the periodic table.

Target 3: I can find an elementís oxidation number (charge) based on its location on the periodic table.

Target 4: I can find an elementís number of valence electrons based on its location on the periodic table.

Target 5: I can identify and explain the general trends of the atomic radius, reactivity (ionization energy),
              and electronegativity of elements both across and down on the periodic table.
