Easy chem question:

Ionic crystals have a relatively high melting point due to strong binding forces between positive and negative ions. T or F?

Metallic crystals are excellent conductors of electricity due to the existence of positive and negative ions. T or F?

I know the first part of both questions is true, but I can't figure out the second part of both questions.
