Week 3 Assignment
1. Classify each example of molecular art as a compound or element. Moreover, where applicable,
specify which of the species are molecules.
A. compound
B. element
C. compound
D. compound
E. compound
F. element
2. In the image below, for each ion, identify the net charge:
a. +2
b. -3
3. Using the figure on the following page on how to achieve an octet for cations and anions, please
draw a Lewis dot structure for each of the following elements. Also, identify what net charge
each element would adopt to achieve the valence electron configuration of a noble gas
(achieve a stable octet). ***See Lithium below as an example.
a. Example: Li Lewis Structure: →Li+ where it has 1+ net charge
b. F
c. Mg
