Properties of Ionic and Covalent Compounds

Front

What is an ionic compound?

Back

An ionic compound is formed when atoms transfer electrons, resulting in the attraction between positively and negatively charged ions. Example: Sodium chloride (NaCl).

Front

What is a covalent compound?

Back

A covalent compound is formed when atoms share electrons. Example: Water (H2O).

Front

What is a key property of ionic compounds regarding melting and boiling points?

Back

Ionic compounds typically have high melting and boiling points due to strong electrostatic forces between ions.

Front

What is a key property of covalent compounds regarding melting and boiling points?

Back

Covalent compounds generally have low melting and boiling points due to weaker intermolecular forces.

Front

How do ionic compounds behave in water?

Back

Ionic compounds dissociate into ions when dissolved in water, allowing the solution to conduct electricity.

Front

How do covalent compounds behave in water?

Back

Covalent compounds do not dissociate into ions in water and typically do not conduct electricity.

Front

What is the electrical conductivity of molten ionic compounds?

Back

Molten ionic compounds conduct electricity because the ions are free to move.

Front

What is the electrical conductivity of molten covalent compounds?

Back

Molten covalent compounds do not conduct electricity as they do not contain free ions.

Front

What is an example of an ionic compound?

Back

Lithium bromide (LiBr) is an example of an ionic compound.

Front

What is an example of a covalent compound?

Back

Carbon dioxide (CO2) is an example of a covalent compound.
