Quartz (SiO₂) is a solid with a melting point of 1550 °C. The bonding in quartz is best described as A)lattice energy. B)network attractions. C)ionic bonding. D)covalent bonding. E)metallic bonding.

Question

Quizplus · Accepted Answer

Quartz consists of a giant covalent network structure in which each silicon atom is covalently bonded to four oxygen atoms and each oxygen atom is covalently bonded to two silicon atoms. This results in a strong three-dimensional network of alternating Si-O-Si bonds, which requires a large amount of energy to break apart, explaining the high melting point of quartz.
