1. Review for Ionic Compounds Test

2. What’s the name of the oxygen anion? What is its dot diagram Oxide O

3. What’s the difference between a monatomic ion and a polyatomic ion? A monatomic ion has one ion with a charge, and a polyatomic ion has more than one atom bonded together with a common charge. Ca +2 = monatomic PO 4 -3 = polyatomic

4. electronegativity What periodic trend explains why nonmetals gain electrons, instead of lose them?

5. Which is more electronegative, metal or non- metal? What does this mean for electrons? Non-metals are more electronegative so they take electrons away from metals.

6. What state of matter are ionic compounds usually found in? Solid with a crystal structure Packet page 4

7. When are ionic compounds good conductors of electricity? When dissolved in water, but NOT WHEN MELTED! Packet page 5

8. Write the Dot Diagram for a Helium atom He

9. Draw the EDD (electron dot diagram) for Calcium phosphide

10. Electrostatic Force What keeps ionic compounds together? Packet Page 3

11. What does the octet rule explain? That (most) atoms will lose or gain electrons to have 8 electrons in the valance shell. This makes atoms stable, like the closest noble gas.
