Chemical Bonding - Ionic Bonding

What is an ionic bond?

• An ionic bond is a type of bond that occurs between two non-metals.

• An ionic bond is formed by sharing electrons between atoms.

• An ionic bond is a type of bond that occurs between two metals.

• An ionic bond is a type of chemical bond that occurs between a metal and a non-metal.

How are ionic bonds formed?

• By sharing protons between atoms

• By the transfer of electrons between atoms

• By the formation of covalent bonds

• By the attraction of opposite charges

Give an example of a compound formed by ionic bonding.

• Carbon dioxide (CO2)

• Hydrogen peroxide (H2O2)

• Sodium chloride (NaCl)

• Ammonia (NH3)

Explain the concept of cations and anions in ionic bonding.

• Anions are positively charged ions, and cations are negatively charged ions.

• Cations repel each other in ionic bonding.

• Cations are positively charged ions, and anions are negatively charged ions. They attract each other in ionic bonding.

• Cations are negatively charged ions, and anions are positively charged ions.

What is the difference between a cation and an anion?

• Cations are larger in size compared to anions.

• Cations are negatively charged ions, and anions are positively charged ions.

• Cations are positively charged ions, and anions are negatively charged ions.

• Cations have a higher atomic number than anions.

Why do ionic compounds have high melting and boiling points?

• Weak magnetic forces between ions

• Strong electrostatic forces of attraction between ions

• Low density of ions in the compound

• Lack of covalent bonds between ions

Discuss the properties of ionic compounds.

• Ionic compounds have low melting and boiling points

• Ionic compounds are insoluble in water

• Ionic compounds do not conduct electricity

• Ionic compounds have high melting and boiling points, are soluble in water, conduct electricity when dissolved in water or molten state, and form crystal lattices.

What is lattice energy in the context of ionic bonding?

• Lattice energy is the energy absorbed when gaseous ions come together to form a solid ionic compound.

• Lattice energy is the energy released when metallic bonds are formed.

• Lattice energy is the energy released when covalent bonds are broken.

• Lattice energy is the energy released when gaseous ions come together to form a solid ionic compound.

Explain the process of dissociation in ionic compounds.

• Ionic compounds combine to form molecules when dissolved in water.

• Dissociation in ionic compounds only occurs in solid form.

• Ionic compounds dissociate into ions when dissolved in water.

• The process of dissociation in ionic compounds involves covalent bonding.

How do you determine the formula of an ionic compound?

• By flipping a coin to decide the formula

• By balancing the charges of the ions involved and writing the formula using the charges as subscripts.

• By asking a magic eight ball for the answer

• By counting the number of vowels in the compound name
