Question

Quizplus · Accepted Answer

Silicates derive their strength from their covalently bonded network structures. This network structure is composed of silicon and oxygen atoms that are bonded together by covalent bonds, forming a three-dimensional framework. This framework is strong and rigid, providing the strength and durability of silicate minerals. The strength of silicates is also enhanced by the presence of other cations, such as aluminum or magnesium, which can substitute for some of the silicon atoms in the framework, further stabilizing the structure.
