Step 4: Model the energy change in the reaction. a) Create an energy graph that illustrates the energy change in the reaction. b) Construct your graph on a blank sheet of paper. Be sure to label the axes, provide a title, and identify

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
