Title: Lecture Periodicity
Description:

Honors Chemistry
November 12, 2020

Go over answers to Periodicity Packet
    organization of periodic table (increasing atomic number)
    trends in size of atom
        as you move down a group (atoms get larger due to greater shielding effect)
        as you move across a period (atoms get SMALLER due to increased coulombic attraction)

Coulombic Attraction
    charge and distance
