- Metals are good conductors of electricity because A) The atoms are lightly packed B) They contain free electrons C) They have high melting point D) All the aboveTo produce alloy metals, the components are heated to a molten state, mixed, and then cooled. The temperature at which the material transitions between a liquid and a solid is a function of the percentages of the components. The liquid and solid states of a material are called phases, and a phase diagram displays the relationship between the percentages of the elements and the transition temperatures.Silicon is considered a.A conductor b.A semiconductor c.An insulator d.A plasma
