Ionic vs. Covalent Bonds

Which type of bond is formed when electrons are transferred from one atom to another?

• Covalent bond

• Ionic bond

• Hydrogen bond

• Metallic bond

In a covalent bond, what do atoms share?

• Protons

• Neutrons

• Electrons

• Ions

Which of the following is typically an ionic compound?

• Water (H2O)

• Carbon dioxide (CO2)

• Table salt (NaCl)

• Methane (CH4)

What type of elements usually form covalent bonds with each other?

• Metals and nonmetals

• Only metals

• Only nonmetals

• Noble gases

Which statement about ionic compounds is true?

• They are usually gases at room temperature

• They have low melting points

• They conduct electricity when dissolved in water

• They are soft and easily deformed

In a water molecule (H2O), what type of bond exists between hydrogen and oxygen?

What is a key difference between ionic and covalent compounds?

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

• Covalent compounds have high melting points, ionic compounds have low melting points.

• Ionic compounds are usually gases at room temperature, covalent compounds are solids.

• Covalent compounds are formed by the transfer of electrons, ionic compounds by sharing electrons.

Which of the following is an example of a covalent compound?

• Sodium chloride (NaCl)

• Potassium bromide (KBr)

• Glucose (C6H12O6)

• Calcium oxide (CaO)

How does the electronegativity difference between atoms affect the type of bond formed?

• A large difference usually results in a covalent bond

• A small difference usually results in an ionic bond

• A large difference usually results in an ionic bond

• Electronegativity difference doesn't affect bond type
