2. _________________ is the base unit of a molecular cpd.


1. In the space below, define Rule of Eight (also called Octet Rule):


2a. There are no atoms of copper in a piece of copper metal (because they have metallic bonds. What two "things" are in this piece of metal,

i) ________________________________________ and


ii) _______________________________________

2b. On the back of paper, draw and label all parts of a piece of metal (i.e. what does metallic look like).


3a. Ionic compounds are made up of ______________

3b. _______________ types of elements produces __________ when they lose electrons.


3c. The other type of element (called ________ ) will do what with their valence electron(s)?: ________________________

3d. What does the ΔEN between the two elements needs to be?


3e. In space below, explain what does the subscript(s) in an ionic compound mean?



3f. On the back of paper, draw and label all parts of an ionic compound. (use Na₁Cl₁ as the ionic compound)


4a. If C and P atom get close enough together so their valence electron interact, will the electrons be shared, transferred (give/take), or all give away (circle one). What is this "bond called"?____________.

4b. What does the ΔEN between the two elements need to be?


4c. In space below, explain what does the subscript(s) in a molecular compound mean?

4d.On the back of paper, draw and label all parts of an molecular compound. (use H₂O₁ as the molecular compound)
