(I)beryllium
(II)carbon
(III)phosphorus
(IV)sulfur

Question

Quizplus · Accepted Answer

Covalent network solids are composed of atoms held together by covalent bonds in a continuous three-dimensional network. Beryllium does not form a covalent network solid, as it typically forms ionic compounds or simple covalent compounds. Carbon and phosphorus both form covalent network solids, with carbon forming diamond and graphite and phosphorus forming white and red phosphorus. Sulfur, while it can form long-chain molecules through covalent bonding, does not typically form a covalent network solid. Therefore, the only elements on the list that form covalent network solids are carbon and phosphorus, making choice C the correct answer.
