1.      How many electrons are in a triple bond? 2.      All elements want to reach octet, which means they want valence electrons to be stable except for hydrogen, helium, phosphorous, sulfur, boron and beryllium.

3.      Draw the electron configuration and write the ion that has 7 electrons.

4.      Answer the following questions using the compound CN-.

a.      Calculate the total number of valence electrons.

b.      Draw the Lewis structure.

c.      Determine the bond angle.

d.      Determine the molecular geometry (shape).

5.      Why does an element gain or lose electrons?

6.      What is a cation and an anion? State the charges that the cation and anion would have.

7.      If an ion has a -3 charge this means that the atom 3 electrons.

8.      Explain why a Cl- atom is bigger in size than a Cl atom?

9.      What type of bond does a dipole moment occur in and why? Then draw the dipole moment in HF (include the partial charges and arrow).

10.  What type of bond is in KBr based on the type of elements. Explain your answer. Then explain if the electrons are shared or transferred.
