21. The plum pudding model A positively charged ball with negatively charged electrons

22. This family has two valence electrons.

23. What are the Alkaline Earth Metals?

24. Silicon shares, rather than loses or gains, electrons.

25. What is a Metalloid?

26. This family is the entire d Block

27. What are the Transition Metals

28. This family has valence electrons that are s2p5

29. What are the Halogens?

31. What are the noble gasses?

32. The plateau during the heating of a solid pure substance represents…

33. The point at which both solids and liquids are found The Melting Point

34. A gas evolves with a strong odor from two chemicals being mixed. There is a lot of heat produced

44. The Lewis Dot Structure for Aluminum

45. .. Al.

46. What is the Electron Configuration and Lewis Dot Structure for Tin Use both long hand and nobel gas configuration

47. Sn: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 2 Sn: [Kr] 5s 2 4d 10 5p 2

48. Why don’t we draw a Bohr model for Titanium?

49. Titanium is in the d-block. Bohr models stop at Ca. The 3d electrons go back to the third energy level rather than continuing on the 4 th energy level

50. If You remove an electron from Potassium, how many Valence electrons does it have? Why would potassium lose an electron?

51. Eight Potassium lost one valence to have the same electron configuration as Argon, thus having eight electrons.
