1. Chemical Bonds Review

2. WHAT DOES THE SYMBOL FOR AN ELEMENT MEAN IN AN ELECTRON DOT DIAGRAM / LEWIS DOT STRUCTURE?

3. NUCLEUS AND ALL NON-VALENCE ELECTRONS

4. WHAT IS THE RATIO OF THE FORMULA KI?

5. 1 TO 1 RATIO

6. IN THE COMPOUND MGCL 2 WHAT DOES THE SUBSCRIPT REPRESENT?

7. 2 ATOMS OF CHLORINE

8. WHAT ARE THE PROPERTIES OF SODIUM CHLORIDE?

9. METAL, CONDUCTOR OF ELECTRICITY, MALLEABLE, DUCTILE

10. WHEN TWO ATOMS OF THE SAME NONMETAL REACT, WHAT DO THEY OFTEN FORM?

11. DIATOMIC MOLECULE

12. WHAT HAPPENS TO THE ELECTRONS IN A POLAR COVALENT BOND?

13. SHARED UNEQUALLY; ONE ELEMENT IS PULLING THE ELECTRONS TOWARDS IT

14. WATER HAS A HIGHER BOILING POINT THAN EXPECTED BECAUSE OF WHAT?

15. STRONG ATTRACTIONS BETWEEN POLAR WATER MOLECULES

16. WHY ARE WATER MOLECULES POLAR AND CARBON DIOXIDE MOLECULES ARE NONPOLAR?

17. WATER HAS A HIGHER BOILING POINT THAN CARBON DIOXIDE

18. WHAT ELEMENTS ARE MOST LIKELY TO FORM MORE THAN ONE TYPE OF ION?

19. TRANSITION METALS

20. WHAT IS A METALLIC BOND?

21. BOND BETWEEN A METAL CATION AND A SHARED POOL OF ELECTRONS

22. WHY CAN MANY METALS BE DRAWN INTO THIN WIRES WITHOUT BREAKING?

23. CATIONS ARE STILL SURROUNDED BY ELECTRONS WHEN THEY SHIFT THEIR POSITIONS IN THE LATTICE

24. WHAT IS AN ALLOY?

25. TWO METALS COMBINED

26. WHAT WOULD HAPPEN IF YOU INCREASED THE AMOUNT OF CARBON IN STEEL?

27. CARBON MAKES THE LATTICE HARDER AND STRONGER

28. IF A METAL HAS MORE VALENCE ELECTRONS WILL IT MAKE THE METALLIC BOND WEAKER OR STRONGER?

29. STRONGER!!

30. THE STRUCTURE IN A METAL LATTICE CAN BE DESCRIBED AS CATIONS SURROUNDED BY A POOL OF SHARED ELECTRONS. WHAT TWO PROPERTIES OF METALS CAN BE EXPLAINED BY THIS STRUCTURE?

31. MALLEABLE, DUCTILE, CONDUCTS ELECTRICITY

32. MIXING MAGNESIUM AND ALUMINUM TOGETHER PRODUCES AN EXCELLENT LIGHTWEIGHT MATERIAL FROM WHICH TO MAKE AIRPLANE PARTS. WHAT IS THIS TYPE OF MIXTURE CALLED?

33. ALLOY

34. WATER DROPLETS TEND TO HAVE A SPHERICAL, ROUND SHAPE. EXPLAIN THIS FACT IN TERMS OF THE POLAR NATURE OF WATER MOLECULES.

35. WATER IS POLAR – STRONG UNEQUAL ATTRACTIONS; MOLECULES ON THE SURFACE OF WATER DROPLETS ARE PULLED TOWARD THE CENTER BY THE ATTRACTIONS TO WATER MOLECULES BELOW THE SURFACE

36. HOW DOES THE ABILITY OF METALS SUCH AS COPPER AND ALLOYS SUCH AS STEEL TO BE DRAWN INTO WIRES AFFECT THE POSSIBLE USES OF THESE MATERIALS?

37. CAN BE DRAWN INTO WIRES TO CONDUCT ELECTRICITY

38. WHAT IS A TYPICAL PROPERTY OF AN IONIC COMPOUND?

39. TENDENCY TO SHATTER WHEN STRUCK

40. HOW ARE METALLIC BONDS SIMILAR TO IONIC BONDS?

41. AN ATTRACTION BETWEEN POSITIVELY CHARGED AND NEGATIVELY CHARGE PARTICLES
