| Question | Answer |
| 1. Under what conditions does an ionic bond conduct electricity? 2. How can you know what type of bond will form between two atoms? | when dissolved in water, look at elements
|
3. Why are the electrons in a metallic bond "delocalized"? 4.How can you know the oxidation # of a transition metal? | they move freely around the metal cations, Roman numerals
| 5. Why do elements form chemical bonds? 6. How does an atom in Group 1 and an atom in Group 15 form a chemical bond?(tell how many electrons are exchanged) | to achieve an octet, atom in group 1 gives away 1 electron and Group 15 gains 3 electrons
| 7. Which compound (of the 3 we discussed) has a low melting point and what does this mean about its bond? 8.Why does Sc form a +3 ion? (What orbitals are electrons lost from?) | covalent/weak bond, loses 2 electrons from s-level and 1 from d-level
| 9. Write the formula for KNO3. 10. Write the name for Mg3N2. | Potassium nitrate, magnesium nitride
| 11. What is the suffix at the end of the anion for a simple binary compound? 12. Why is NaF2 incorrect? | -ide, Na only loses 1 electron and has a +1 charge
| 13. Name this compound: BaOH2 14. The more reactive an atom, the higher its potential energy. Does Ne or F have higher potential energy? Explain. | Barium hydroxide, F because it is very reactive and Ne is stable
| 15. What ion will Al form and why? 16.Name this compound: PbF2 | Al +3 because it loses 3 electrons, Lead(II) fluoride
| 17. Why are most ionic compounds "electrolytes"? 18. Write the formula formed when Cs and N bond. | They conduct current when dissolved in water, Cs3N
| 19. What is the overall charge of a compound after it is bonded? 20. Name this compound: Sr(NO3)2 | neutral, Strontium nitrate
| 21. Write the formula for Sodium sulfide 22. Draw an electron-dot diagram for the bond between K and I. | Na2S, KI (1 electron given and 1 taken)
| 23. What is a polyatomic ion? 24. How does sulfite differ from sulfate? | group of 2 or more nonmetal atoms that has a charge, sulfite has 1 fewer Oxygen atom
| 25. How does an atom get an oxidation number? 26. How does a cation differ from an anion? | from the # of electrons lost or gained in bonding, cation is positive ion and anion is negative ion
| 27. Write the formula for Copper(II)acetate. 28. Covalent compounds are called __________. | Cu(C2H3O2)molecules
| 29. Brass is a mixture of Z and Cu. This is called a(n)___________.30. Pr is an element with the configuration [Xe]4f36s2. Explain how it gets a charge of +3 | alloy,loses 3 f-orbital electrons |
