Answer 1

Answer:

Ductilityis the answer

Answer 2

1. The correct option is b.

• Metals are highly conductive of heat and electricity
• Metals are hard, malleable, ductile and sonorous.

2. The correct option is b.

• Calcium, potassium, and sodium are soft metals and can be cut easily.
• Iron is a hard metal

3. The correct option is c.

• All metals like iron, copper and Al are good conductors of heat and electricity.
• Carbon is a non-metal so, not a good conductor of electricity

4. The correct option is c.

• Calcium, potassium, and sodium, Mg are soft metals and can be cut easily.
• Gold is a hard and malleable metal.

5. The correct option is b.

• Graphite conducts electricity.
