Chapter 10: Q71E. (page 592)

Classify each substance in the table as either a metallic, ionic, molecular, or covalent network solid

Short Answer

Expert verified

X is ionic, Y is metallic and Z is covalent network solids.

Step by step solution

01

To classify each substances

Metallic solid

Covalent solid

Molecular solid

Ionic solid

Electrical conductivity

Good conductors of heat and electricity

Poor conductors of heat and electricity

Poor conductors of heat and electricity

Poor conductors of heat and electricity

Melting point

Melting point depends strongly on electronic configuration

high

Low

Relatively high melting point

Appearance

Malleable, ductile, lustrous

Hard,brittle and dull

Soft and dull surface

Hard,brittle and dull

Solubility in water

Insoluble

Insoluble

Insoluble

soluble

Hence Based on the table shown in the detailed section we can say that X is ionic, Y is metallic and Z is covalent network solids.
