Understanding Ionic Compounds

What is an ionic bond?

• An ionic bond is a chemical bond formed through the electrostatic attraction between oppositely charged ions.

• A temporary attraction between neutral molecules.

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

• A bond that occurs only in metals.

Name two types of ions.

• Electrons and Photons

• Protons and Neutrons

• Molecules and Compounds

• Cations and Anions

List three properties of ionic compounds.

• 1. High melting and boiling points, 2. Solubility in water, 3. Electrical conductivity when dissolved in water or molten.

• Insoluble in water

• Low melting points

• Poor electrical conductivity in any state

How do you name the compound NaCl?

• Sodium bicarbonate

• Sodium phosphate

• Sodium sulfate

• Sodium chloride

What is the formula for calcium chloride?

• CaCl3

• CaCl2

• CaCl

• Ca2Cl

Explain one application of ionic compounds in daily life.

• Calcium carbonate is an ionic compound used in toothpaste.

• Copper sulfate is an ionic compound used in fertilizers.

• Table salt (sodium chloride) is an ionic compound used in cooking and food preservation.

• Sugar (sucrose) is an ionic compound used in baking.

What charge does a sodium ion carry?

• -1

• 0

• +1

• +2

Describe how ionic compounds are formed.

• Ionic compounds are formed by the transfer of electrons from metals to non-metals, resulting in the formation of cations and anions that attract each other.

• Ionic compounds are formed through the fusion of liquid metals at high temperatures.

• Ionic compounds are created when two metals combine to form a solid.

• Ionic compounds are formed by the sharing of electrons between two non-metals.

What is the significance of the formula in ionic compounds?

• The formula signifies the ratio and types of ions in an ionic compound, ensuring charge balance.

• The formula indicates the temperature stability of the compound.

• The formula determines the color of the ionic compound.

• The formula represents the physical state of the compound at room temperature.

Why are ionic compounds typically solid at room temperature?

• Ionic compounds are typically solid at room temperature due to the strong ionic bonds forming a rigid lattice structure.

• Ionic compounds are liquid at room temperature due to weak molecular forces.

• Ionic compounds are solid because they have low melting points.

• Ionic compounds are solid due to the presence of metallic bonds.
