Ionic Bonding

Mr. Anderson explains ionic bonding, highlighting the transfer of electrons from one atom to another, forming cations and anions. Using sodium chloride as an example, he discusses the stability of ionic compounds, the role of Coulomb's Law, and the concept of lattice energy. The video also compares different ionic compounds, emphasizing the impact of ion size and charge on lattice energy and bond strength.

What is the main difference between ionic and covalent bonding?

• Ionic bonding involves transferring electrons.

• Covalent bonding involves losing electrons.

• Covalent bonding involves transferring electrons.

• Ionic bonding involves sharing electrons.

What is a cation?

• An ion with a negative charge.

• An ion that has gained an electron.

• An ion with a positive charge.

• An ion that has lost a proton.

According to Coulomb's Law, what happens when the distance between ions increases?

• The charge of ions decreases.

• The attraction between ions increases.

• The attraction between ions decreases.

• The charge of ions increases.

How does the size of an ion affect lattice energy?

• Ion size has no effect on lattice energy.

• Larger ions increase lattice energy.

• Smaller ions decrease lattice energy.

• Smaller ions increase lattice energy.

What happens to lattice energy when the charge of ions increases?

• Lattice energy remains the same.

• Lattice energy becomes zero.

• Lattice energy decreases.

• Lattice energy increases.
