Properties Of Ionic Compounds Trivia Quiz - Quiz

Do you have enough knowledge about ionic compounds and their properties? If yes, play this trivia quiz and prove it to us. An ionic compound in chemistry is a chemical compound made up of ions (cations and anions) that are held by electrostatic forces, commonly known as ionic bonding. Here, we have asked some questions related to those bonds. So, if you think you can easily answer the questions asked here. Take the quiz now. All the best, buddy!

Questions and Answers

1.

Why do ionic compounds have such high melting and boiling points?
- A.
  
  The electrostatic forces of attraction between the positive and negative ions holding the lattice together are very strong and a lot of energy is required to break them apart.
- B.
  
  The electrostatic forces of attraction between the positive ions holding the lattice together are very strong and a lot of energy is required to break them apart.
- C.
  
  The electrostatic forces of attraction between the positive and electrons holding the lattice together are very strong and a lot of energy is required to break them apart.
- D.
  
  The electrostatic forces of attraction between the cations and anions holding the lattice together are very weak and a less energy is required to break them apart.
2.

Why are ionic compounds brittle (shattered) when it is hit with a hammer?
- A.
  
  When hit with a hammer, the like-charged ions line up together and they draw closer together due to electrostatic attraction and this causes the ionic compound to shatter.
- B.
  
  When hit with a hammer, the opposite-charged ions line up together and they attract due to electrostatic forces and this causes the ionic compound to shatter.
- C.
  
  When hit with a hammer, the like-charged ions line up together and they repel due to electrostatic repulsion and this causes the ionic compound to shatter.
- D.
  
  When hit with a hammer, the cations disperse and they repel due to electrostatic repulsion and this causes the ionic compound to shatter.
3.

Indicate whether the following atoms will form cations and explain why.
- A.
  
  Flourine. Reason- metal forms cation as it tends to lose electrons.
- B.
  
  Calcium. Reason - non-metal forms cation as it tends to gain electrons
- C.
  
  Flourine. Reason - non-metal forms cation as it tends to lose electrons.
- D.
  
  Calcium. Reason - metal forms cation as it tends to lose electrons.
4.

5.

When the ions in each pair combine to form ionic compounds, what will be the ratio of metal ion to non-metal ion? Mg²⁺ and Cl^-
- A.
  
  2 Mg ²⁺: 1 Cl^-
- B.
  
  1 Mg ²⁺: 2 Cl^-
- C.
  
  2 Mg ²⁺: 3 Cl^-
- D.
  
  1 Mg ²⁺: 1 Cl^-
