Ionic compounds are compounds made up of ions. Take this naming ionic compounds quiz today to find out how well you understand the concept! An ionic compound is formed by the complete transfer of electrons from one atom to another–often from a metal to a nonmetal–and the resulting ions have achieved an octet. Below is a chemistry quiz on ionic compounds, names, and formulas.

Put your knowledge to the test and see how many correct answers you can achieve. Take the plunge into the fascinating realm of chemical naming and discover the satisfaction of mastering the language of chemistry. Ready Read moreto accept the challenge?

Naming Ionic Compounds Questions and Answers

1.

Select the name of LiNO₃.
- A.
  
  Lithium nitrogen trioxide
- B.
  
  Lithium nitride
- C.
  
  Lithium nitrite
- D.
  
  Lithium nitrate
- E.
  
  Lithium nitrogen oxygen
Correct Answer
D. Lithium nitrate

Explanation
LiNO3 is the chemical formula for lithium nitrate. It is composed of one lithium ion (Li+) and one nitrate ion (NO3-). The name "lithium nitrate" accurately reflects the composition of the compound, as it contains lithium and nitrate ions. The other options, such as "lithium nitrogen trioxide" and "lithium nitrite," do not accurately represent the composition of LiNO3. Therefore, the correct answer is lithium nitrate.

Select the name of Na₂CO₃.
- A.
  
  Sodium carbonate
- B.
  
  Disodium carbonate
- C.
  
  Disodium carbon trioxide
- D.
  
  Sodium carbon trioxide
- E.
  
  Sodium carbonite
Correct Answer
A. Sodium carbonate

Explanation
Sodium carbonate is the correct answer because it is the common name for Na2CO3. It is a white, crystalline solid that is commonly used in various industries such as glass manufacturing and water treatment. The other options, disodium carbonate, disodium carbon trioxide, sodium carbon trioxide, and sodium carbonite, are not the correct names for Na2CO3.

Select the name of (NH₄)₃N.
- A.
  
  Tetrahydrogen nitride nitrogen
- B.
  
  Tetranitrogen didecahydrogen
- C.
  
  Triaminonitride
- D.
  
  Ammonium nitride
- E.
  
  Triammonium nitrogen
Correct Answer
D. Ammonium nitride

Explanation
The correct answer is ammonium nitride because (NH4)3N is formed by combining the ammonium ion (NH4+) and the nitride ion (N3-). The ammonium ion consists of one nitrogen atom bonded to four hydrogen atoms, while the nitride ion consists of one nitrogen atom with a charge of -3. Therefore, when these two ions combine, they form (NH4)3N, which can be referred to as ammonium nitride.

Select the name of K₃P.
- A.
  
  Kryton phosphorous
- B.
  
  Potassium phosphide
- C.
  
  Trikrypton phosphide
- D.
  
  Trikrypton phosphorous
- E.
  
  Potassium phosphorous
Correct Answer
B. Potassium phosphide

Explanation
Potassium phosphide is the correct answer because the chemical formula for potassium phosphide is K3P. This compound is formed by the combination of potassium (K) and phosphorous (P). The other options either have incorrect chemical formulas or do not represent the correct combination of elements.

What is the correct formula for gallium hydroxide?
- A.
  
  Ga(OH)3
- B.
  
  Gl3O
- C.
  
  Ga3O2
- D.
  
  Gl(OH)2
- E.
  
  Ga(HO)2
Correct Answer
A. Ga(OH)3

Explanation
The correct formula for gallium hydroxide is Ga(OH)3. This is because gallium is a metal with a +3 charge, and hydroxide is a polyatomic ion with a -1 charge. To balance the charges, three hydroxide ions are needed for every gallium ion, resulting in the formula Ga(OH)3. The other options, Gl3O, Ga3O2, Gl(OH)2, and Ga(HO)2, do not correctly represent the combination of gallium and hydroxide ions.

Select the formula for strontium chloride.
- A.
  
  SrCl2
- B.
  
  SrCl
- C.
  
  Sr2Cl3
- D.
  
  SrClO2
- E.
  
  SrClO3
Correct Answer
A. SrCl2

Explanation
The correct formula for strontium chloride is SrCl2. This formula indicates that there is one strontium ion (Sr) and two chloride ions (Cl) in the compound. The subscript "2" after Cl indicates that there are two chloride ions present.

Select the formula for aluminum sulfide.
- A.
  
  Al2(SO4)3
- B.
  
  AlS
- C.
  
  Al2S3
- D.
  
  Al3(SO3)2
- E.
  
  AlSO3
Correct Answer
C. Al2S3

Explanation
The correct formula for aluminum sulfide is Al2S3. This is because aluminum has a +3 charge and sulfur has a -2 charge. In order to balance the charges, two aluminum atoms are needed to combine with three sulfur atoms, resulting in the formula Al2S3.

What is BaO?
- A.
  
  Beryllium Oxide
- B.
  
  Barium Oxide
- C.
  
  Aluminum Oxide
- D.
  
  Potassium Oxide
Correct Answer
B. Barium Oxide

Explanation
BaO is the chemical formula for Barium Oxide. Barium Oxide is a white crystalline solid that is commonly used in the production of ceramics, glass, and other materials. It is also used in the manufacture of certain types of barium compounds, as well as in the production of certain types of catalysts. Barium Oxide is highly reactive and can react with water to form Barium Hydroxide, which is a strong base. It is important to handle Barium Oxide with caution due to its reactivity and potential health hazards.
