29. A chemist would use this separation technique to separate a mixture of water and alcohol.

30. What is distillation?

31. The ion P -3 has this many electrons.

32. What is 18?

33. The number of protons added to the number of neutrons gives me this.

34. What is mass number?

35. Rutherford discovered this with his gold foil experiment.

52. What is the alkaline earth metals?

53. This element is located in Group 4A and period 5.

54. What is Tin?

55. Elements within a group have similar properties because they share this common feature.

56. What is- they share the same number of valence electrons?

57. This states that when the elements are arranged by increasing atomic number, their physical and chemical properties show a pattern.

58. What is periodic law?

60. This periodic trend decreases as you move across the period and increases as you move down a group.
