Today we took notes on what happens to the atomic radius, electronegativity, ionization energy, and reactivity as you go across a period (row) and down a group (column) on the periodic table.
All the trends can be explained by whether you are adding electrons to the same energy level or whether you are adding a whole new energy level.
Turn in your graphing assignment with three graphs as well as lab 10A.
Tomorrow: Quiz on electron configurations
