Note: Some questions below assume that students have learned the Periodic Trend, Electronegativity (EN).
Answer the following questions using your general chemistry knowledge and information from Basic Particles and How Atoms Group Together.
1) Circle which of the following two atoms would most likely share their valence electrons (ve-)?
a) Al - Al b) C - O c) Ca - Cl d) Fe - N
2a) What do you call the "bond" if the ve- are being lost by one atom and taken by the other atom?
2b) What causes (not sufficient to just state EN need to explain) this "transfer" when these two atoms get close together?
2c) What Base particles (give name of both of them) do you have as a result of this "transfer"?
3) What are the 2 other possible ways ve- are moved when two atoms get close and state their "bonding" name.

4) For chemist, which of the above 3 possible ways that ve- moves is the ONLY CHEMICAL BOND?
5) What is the name of the Base particle when two atoms SHARE their ve-?
6) In general, what two types of elements would come together to form a "ionic" bond?
7) Yes, the EN difference determines how the ve- move when two atoms get close together, but what determines HOW MANY ve- move?
8) Define the Rule of Eight:
9) Circle which of the following pairs of elements would most likely form an "ionic" bond?
a) Al - Al b) C - O c) Ca - Cl d) F - N
10) What is the ΔEN for "Ionic bond" ______ , Covalent bond ______.
