You are given a gray substance that melts at 700 °C; the solid is a conductor of electricity and is insoluble in water. Which type of solid (molecular, metallic, covalent-network, or ionic) might this substance be?
(a) Draw a picture that represents a crystalline solid at the atomic level.
(b) Now draw a picture that represents an amorphous solid at the atomic level.
