Properties of Ionic and Covalent Compounds

Front

What are covalent compounds?

Back

Covalent compounds are chemical compounds formed by the sharing of electrons between atoms. They typically have low melting points and do not conduct electricity when dissolved in water.

Front

What are ionic compounds?

Back

Ionic compounds are chemical compounds formed by the transfer of electrons from one atom to another, resulting in the formation of ions. They usually have high melting points and conduct electricity when dissolved in water.

Front

What is the melting point of covalent compounds?

Back

Covalent compounds generally have low melting points, often below 200°C.

Front

How do covalent compounds behave in water?

Back

When dissolved in water, covalent compounds do not conduct electricity well.

Front

How do ionic compounds behave in water?

Back

When dissolved in water, ionic compounds dissociate into ions and conduct electricity well.

Front

What is an example of a covalent compound?

Back

An example of a covalent compound is PBr5 (phosphorus pentabromide).

Front

What is an example of an ionic compound?

Back

An example of an ionic compound is LiBr (lithium bromide).

Front

What is the difference in electrical conductivity between ionic and covalent compounds in solution?

Back

Ionic compounds conduct electricity in solution, while covalent compounds do not.

Front

What type of bond is formed in ionic compounds?

Back

Ionic compounds are formed by ionic bonds, which involve the electrostatic attraction between positively and negatively charged ions.

Front

What type of bond is formed in covalent compounds?

Back

Covalent compounds are formed by covalent bonds, which involve the sharing of electron pairs between atoms.
