Ionic and Covalent Bonds

How do Ionic Compounds conduct electricity?

• Ionic compounds conduct electricity when solid due to fixed ions.

• Ionic compounds conduct electricity when dissolved in water or melted, as the ions are free to move.

• Ionic compounds do not conduct electricity in any state.

• Ionic compounds conduct electricity only at high temperatures.

Example of an Ionic Compound?

• Sodium chloride (NaCl)

• Calcium carbonate (CaCO3)

• Glucose (C6H12O6)

• Iron (III) oxide (Fe2O3)

What is the typical melting point of Covalent Compounds?

• Covalent compounds generally have high melting points.

• Covalent compounds generally have low melting points.

• Covalent compounds have melting points that vary widely.

• Covalent compounds have very high melting points.

Example of a Covalent Compound?

• Water (H2O)

• Sodium Chloride (NaCl)

• Calcium Carbonate (CaCO3)

• Iron Oxide (Fe2O3)

How do Covalent Compounds conduct electricity?

• Covalent compounds generally do not conduct electricity, as they do not have free ions.

• Covalent compounds conduct electricity when dissolved in water.

• Covalent compounds conduct electricity due to the presence of free electrons.

• Covalent compounds can conduct electricity in solid form.

What is the typical melting point of Ionic Compounds?

• Ionic compounds generally have low melting points.

• Ionic compounds generally have moderate melting points.

• Ionic compounds generally have high melting points.

• Ionic compounds do not have a defined melting point.

What is a Covalent Bond?

• A type of bond where atoms share one or more pairs of electrons.

• A bond formed by the transfer of electrons from one atom to another.

• A weak attraction between molecules due to temporary dipoles.

• A bond that occurs only in ionic compounds.

Are Covalent Compounds soluble in water?

• Yes, they are highly soluble in water.

• No, they are generally insoluble in water.

• Covalent compounds can be less soluble in water, especially organic ones.

• Covalent compounds are always soluble in water.

What is an Ionic Bond?

• A type of bond formed by sharing electrons between atoms.

• A type of bond formed through the electrostatic attraction between oppositely charged ions.

• A bond that occurs only in metals.

• A bond that involves the transfer of protons between atoms.

What are the properties of Ionic Compounds?

• Ionic compounds have low melting and boiling points and are malleable.

• Ionic compounds typically have high melting and boiling points, are brittle, and conduct electricity when dissolved in water.

• Ionic compounds are always gases at room temperature and do not conduct electricity.

• Ionic compounds are soft and can be easily shaped.
