Question

Amanda is presented with a piece of metal and asked to determine its physical

Answer 1

Answer: magnetism, electrical conductivity, high melting point

Explanation: Physical properties of metals include: ductility, magnetism, malleability, high electrical conductivity, high density, high melting and high boiling point.

Magnetism is the property of metals which makes them to be attracted by magnets.

Metals are good conductors of electricity because their valence electrons are free to move through out the solid.

Metals have high melting points because of the strong bonds existing between valence electrons and nuclei. High energy is required to break the strong bonds between the nucleus and the valence electrons in order for the metals to melt. This means that metals melt at high temperatures.

Answer 2

Answer:

D. magnetism, electrical conductivity, high melting point

Explanation:

Magnetism is the property of metal due to which they are attracted by magnets. Metals have high electrical conductivity which means they are good conductors of electricity. They also have high melting points i. e. they require high amount of heat to change its solid state into liquid state. In melting, bonds are broken down due to the applicable of heat energy.
