Ionic and Covalent Properties DOL

Front

What type of material typically has a high melting point?

Back

Ionic materials generally have high melting points due to the strong electrostatic forces between ions.

Front

What type of material is characterized by a low boiling point?

Back

Covalent materials often have low boiling points because they consist of molecules held together by weaker van der Waals forces.

Front

Which type of material is typically soluble in water?

Back

Both ionic and covalent materials can be soluble in water, but ionic compounds usually dissolve well due to their dissociation into ions.

Front

What is the chemical formula for phosphorus pentabromide?

Back

PBr5 is a covalent compound.

Front

Which type of material does not form electrolyte solutions?

Back

Covalent materials do not form electrolyte solutions because they do not dissociate into ions in solution.

Front

What is the primary characteristic of ionic bonds?

Back

Ionic bonds are formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is a key characteristic of covalent bonds?

Back

Covalent bonds are formed when two atoms share one or more pairs of electrons.

Front

How do ionic compounds behave in water?

Back

Ionic compounds typically dissociate into their constituent ions when dissolved in water, allowing them to conduct electricity.

Front

What is an example of a covalent compound?

Back

An example of a covalent compound is water (H2O), where hydrogen and oxygen share electrons.

Front

What is the general state of ionic compounds at room temperature?

Back

Ionic compounds are usually solid at room temperature.
