1) Find the elements sodium, oxygen, and phosphorus on the periodic table. Describe the monoatomic ions each would form. Then, given what you know about chemical bonding, describe and give the formulas for the types of ionic compounds they would produce with each other.
2) Ancient sword makers originally used copper to make swords. Later, they found bronze to work better, but it was still soft and was not durable. In the early Middle Ages, sword makers used iron to make swords, but the swords were not durable or flexible, and they rusted easily. In the later Middle Ages, sword makers produced steel swords, which were strong, flexible, less resistant to rust, and could hold an edge. Given your knowledge of alloys, explain the properties of each improvement.
