Do Now 11/14
1. Last week we investigated coulombic
attraction.
a. What is coulombic attraction?
b. Does coulombic attraction increase or decrease
as you move down a group? Why?
c. Does coulombic attraction increase or decrease
as you move left to right across a period? Why?
Do Now 11/17
1. Describe and explain the pattern for metal
reactivity
a. As you move from bottom to top on the periodic
table.
b. As you move from right to left on the periodic table.
2. Often non-metals react by gaining extra electrons
(trying to get to 8 on the outside shell). Use
coulombic attraction to predict which non-metal
is the most reactive.
