17. Bonds 200 A compound made by transferring electrons Answer: ionic

18. Bonds 300 A compound made by sharing electrons. Answer: covalent

19. Bonds 400 Which bond has the most drastic difference in electronegativity values? Answer: ionic

20. Bonds 500 Which bond is formed when atoms have similar electronegativity values? Answer: covalent

21. Bonds 600 Which bond is formed when two atoms from opposite sides of the periodic table join? Answer: ionic

22. Miss Alanious 100 Ionic compounds in a solid form a Answer: Crystal Lattice.

23. Miss Alanious 200 Solid ionic compounds do not conduct electricity because Answer: They are in a fixed position, have a strong attraction for each other, and electricity is not free to flow.

24. Miss Alanious 300 The rule for solubility is Answer: Like dissolves like

25. Miss Alanious 400 Why doesn’t PURE water conduct electricity well? Answer: The total charge of water overall is neutral.

26. Miss Alanious 500 What do high numbers on the conductivity meter show? Answer: ions are present and electrons are allowed to move freely.

27. Miss Alanious 600 Why did the stream of water bend when the NEGATIVELY charged knife was brought near it? Answer: The positive part of the water molecule was attracted to the knife.

28. Final Jeopardy What happened to the arrangement of water molecules in the stream as they passed the negatively charged knife?

29. Answer The started out randomly and then aligned with the positive hydrogen towards the knife
