Which statement best describes the structure of covalent network solids? a. they are giant structures held together by weak forces of attraction. b. all the atoms are covalently bonded to other atoms to form a lattice-like structure. c. several covalently bonded molecules form covalent bonds with each other. d. they consist of a network of atoms alternately bonded by covalent and ionic bonds.

Option (B) is the correct answer.

Explanation:

A covalent compound is a compound formed by sharing of electrons. And, in a covalent network solid atoms are bonded by covalent bonds in a continuous network that is extending throughout the material or solid.

This continuous arrangement of atoms are like a lattice.

For example, diamond is a covalent network solid in which carbon atoms are arranged in a continuous lattice like structure.

Hence, we can conclude that the statement all the atoms are covalently bonded to other atoms to form a lattice-like structure, best describes the structure of covalent network solids.
