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 can you identify an ionic compound?

Back

Ionic compounds typically consist of a metal and a non-metal, have high melting and boiling points, and conduct electricity when dissolved in water.

Front

How can you identify a covalent compound?

Back

Covalent compounds usually consist of non-metals, have lower melting and boiling points compared to ionic compounds, and do not conduct electricity.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between oppositely charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What are some properties of ionic compounds?

Back

Ionic compounds are usually solid at room temperature, have high melting and boiling points, and are soluble in water.

Front

What are some properties of covalent compounds?

Back

Covalent compounds can be gases, liquids, or solids at room temperature, have lower melting and boiling points, and are often not soluble in water.

Give an example of an ionic compound and its use.

Back

Example: Calcium chloride (CaCl2) is used for de-icing roads.

Front

Give an example of a covalent compound and its use.

Back

Example: Carbon dioxide (CO2) is used in carbonated beverages.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged entity composed of two or more atoms bonded together, such as sulfate (SO4^2-).
