  1. Bonding Questions Answer in your online lab notebook.

  2. Question #1 • If two atoms are sharing electrons, which type of bond is holding them together?

  3. Question #2 Beryllium has an atomic # of 4. How many electrons are in the 1st energy level? How many electrons are in the 2nd energy level.

  4. Question #3 • Supposedly ionic bonds are very strong. What is a physical characteristic demonstrated by elements in ionic bonds that supports the above statement?

  5. Question #4 • Which type of bond do you most likely have if a non-metal is bonding with a non-metal?

  6. Question #5 • Which type of bond do you most likely have if a metal is bonding with a non-metal?

  7. Question #6 • Which type of bond do you have if a metal is bonded to another metal?

  8. In the following questions you might need the periodic table. Periodic table sites: www.chemicalelements.com or www.webelements.com

  9. Question #7 • On paper or in your head, picture the electron-dot structure of Argon (Ar). How many dots are circling Argon?

  10. Question #8 • What other element on the periodic table might be a good match for Argon? Why?

  11. Question #9 • The chemical formula for water is H2O. Water has 2 hydrogen atoms covalently bonded to one oxygen atom. Explain why water is a happy, stable atom.

  12. Question #10 • In a basic sense, electricity is the movement of electrons from molecule to molecule. Out of covalent, ionic, and metallic bonds which one will conduct electricity the best? Why?

  13. For Questions #11 through #18 list which type of bond the molecule most likely has.

  14. Choose between ionic, covalent, and metallic. • Question #11 -- HCl • Question #12 -- Cu3Zn2 • Question #13 -- H2O2 • Question #14 -- KCl • Question #15 -- C3H8 • Question #16 -- Na2O

  15. Question #17 • Bronze is an alloy (a combination of metals) made from copper (Cu) and Tin (Sn). Which type of bond holds the atoms in the molecule bronze together?

  16. Question #18 • Explain why Carbon can create so many different molecules?

  17. Question #19 • Carbon Dioxide (CO2), a favorite molecule for those of us who are green, is pictured below. Does CO2 contain ionic, covalent, or metallic bonds? Does CO2 contain single, double, or triple bonds? O C O

  18. Question #20 • Why are molecules that have covalent bonds more likely to have a lower boiling point?
