Short answer.

1. Differentiate between soft and hard steel. Hint. Refer back to the Tempering of Steel Laboratory.Hard Steel- steel that was heated and cooled quickly, resulting in small crystals. Breaks easily when bent.Soft Steel- steel that was heated and cool slowly, resulting in long crystals. Bends when a force is applied

2. Is it possible for a bond to be partially ionic? Explain.No. In an ionic bond entire electrons are transferred to result in a full charge.

3. What is an ion? How does it form?An ion is any charged species of an element that is formed by the loss or gain of electrons. Cations (+) Anions (-).

4. Why do atoms bond? Explain.

Bonding ReviewAtoms bond to become more stable. The action of bonding is carried out by the transferring or sharing of electrons to arrive at a full outside shell, 8 valence electrons.

5. What is a polyatomic ion? What kind of bond holds the atoms in a polyatomic ion together?A polyatomic ion is a covalently bound molecule whose atoms collectively form a charge due to the unequal sharing of electrons.

6. What is the sea of electrons and how does that allow for conductivity, malleability, and ductility?The sea of electrons describes how metallic compounds are structured. The ions float while being surrounded by electrons that are available to form new bonds (malleability/ductility) or migrate in the same direction (conductivity).

7. What are alloys? What is the benefit of an alloy?An alloy is a mixture of metals that result in the retention of original physical and chemical properties.
