Identifying Compounds Ionic vs Covalent

Front

What is an ionic compound?

Back

An ionic compound is formed when atoms transfer electrons, resulting in the formation of charged ions that attract each other. Example: Sodium chloride (NaCl).

Front

What is a covalent compound?

Back

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

Front

How do you identify an ionic compound?

Back

Ionic compounds typically consist of a metal and a non-metal, and they have high melting and boiling points.

Front

How do you identify a covalent compound?

Back

Covalent compounds usually consist of non-metals and have lower melting and boiling points compared to ionic compounds.

Front

What is the difference in electron behavior between ionic and covalent compounds?

Back

In ionic compounds, electrons are transferred; in covalent compounds, electrons are shared.

Front

What are some properties of ionic compounds?

Back

Ionic compounds are usually solid at room temperature, conduct electricity when dissolved in water, and have high melting points.

Front

What are some properties of covalent compounds?

Back

Covalent compounds can be gases, liquids, or solids at room temperature, do not conduct electricity, and have lower melting points.

Front

What is an example of an ionic compound?

Back

Sodium chloride (NaCl) is a common example of an ionic compound.

Front

What is an example of a covalent compound?

Back

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

Front

What role do electronegativity values play in determining bond type?

Back

Electronegativity values help determine whether a bond is ionic or covalent; a large difference indicates ionic, while a small difference indicates covalent.
