BUILDING UNDERSTANDINGS
11. How many protons and electrons does oxygen have? What about hydrogen? (Draw a
model of each atom if that helps you think about the differences between them.)
12. What have we figured out about attractions between oppositely charged particles?
13. If we put these ideas together, how can we explain the partial negative charge on oxygen
and the partial positive charge on hydrogen?
14. How do partial charges affect attractions between water molecules? Draw several water
molecules, and use dotted lines to draw where one molecule is attracted to another
molecule. (You can either insert a Google Doc Drawing or you can draw it on either paper or
your whiteboard, take a picture, and then insert into the blue box below.)

15. How does this help us explain why water molecules stek together?
BACK TO THE SIMULATION (Check out mineral oil, again in "opaque" surface view.)
16. Is mineral oil a symmetrical molecule? Does it have partial charges?
17. Think back to lesson 3 and when we put drops of liquids on pennies. Could we get many
drops of oil to stick on a penny? What can we infer about attractions between mineral oil
molecules? Do we think it is a polar molecule?
