Transcript text: Describe the difference between molecular and ionic compounds.

Solution

Solution Steps

Step 1: Define Molecular Compounds

Molecular compounds are formed when two or more nonmetals share electrons, creating covalent bonds. These compounds typically have low melting and boiling points and do not conduct electricity in any state.

Step 2: Define Ionic Compounds

Ionic compounds are formed when a metal transfers electrons to a nonmetal, creating ions that are held together by electrostatic forces. These compounds generally have high melting and boiling points and conduct electricity when dissolved in water or melted.

Step 3: Compare Properties

Molecular compounds:

Formed by covalent bonds.
Low melting and boiling points.
Poor conductors of electricity.

Ionic compounds:

Formed by ionic bonds.
High melting and boiling points.
Good conductors of electricity in aqueous or molten state.

Final Answer

\(\boxed{\text{Molecular compounds are formed by covalent bonds between nonmetals, while ionic compounds are formed by ionic bonds between metals and nonmetals.}}\)
