H Chemistry- Extra Credit 2/10/15

Go to the following site and complete the assignment. Then answer the questions below.

http://www.pbslearningmedia.org/resource/lsps07.sci.phys.matter.ionicbonding/ionic-bonding/

Questions:
1. Why do ionic bonds form between metals and nonmetals?
2. In the activity, when Na lost an e- it shrank and the Cl+ grew in size. Does that say anything about the location of the electron before and after it was transferred?
3. Why can different numbers of metal and nonmetal atoms create ionic bonds together?
