Ionic Bonding Practice Quiz
A small, 7-question practice quiz on Ionic Bonding at www. Thechemwhiz. Piczo. Com
- 1.
When can ionic bonds be formed?
- A.
When there is a metal and a nonmetal.
- B.
When there are two solids.
- C.
When there are nonmetals.
Correct Answer
A. When there is a metal and a nonmetal.Explanation
Ionic bonds can be formed when there is a metal and a nonmetal present. This is because metals tend to lose electrons and become positively charged ions, while nonmetals tend to gain electrons and become negatively charged ions. The attraction between these oppositely charged ions leads to the formation of ionic bonds.Rate this question:

If in the process of ionic bonding, would Nitrogen be an cation or an anion?
Correct Answer
Anion
anion.Explanation
Nitrogen is a nonmetal. Nonmetals gain electrons and become negatively charged ions.
Negatively charged ions are called anions.Rate this question:

Lithium has a charge of +1 and Nitrogen has a charge of -3. What would be the name of the compound, in terms of letters AND in terms of chemical symbols? (Note: Subscripts cannot be used, so interpret the numbers in the chemical formulas as subscripts).
- A.
Lithium Nitride and LiN3
- B.
Trilithium Nitrogen and Li3N
- C.
Lithium Nitride and Li3N
- D.
Trilithium Nitride and LiN
Correct Answer
C. Lithium Nitride and Li3NExplanation
All ionic compounds have the metal first, and the nonmetal second. The nonmetal always ends in -IDE.
So Lithium and nitrogen would create Lithium Nitride.
Nitrogen needs 3 electrons, and one atom of Lithium can only give 1 electron.
So, there needs to be three atoms of Lithium to give 3 electrons to one atom of Nitrogen.
So, you put "3" in front of Lithium to say that there has to be 3 Lithium electrons. You don't put anything in front of Nitrogen because there is only 1 atom needed.
So, the formula will be Li3N.Rate this question:

Nickel (II) has a charge of +2. Chlorine has a charge of -1. What is the name of the compound and what is the formula of the compound?
- A.
Nickel (II) Chloride and NiCl2
- B.
Nickel Chloride and NiCl2
- C.
Nickel Chlorine and NiCl
- D.
Nickle (II) Chloride and Ni2Cl
Correct Answer
A. Nickel (II) Chloride and NiCl2Explanation
Nickel is one of the elements that doesn't have only charge, but many different possible charges.
The roman numeral II means 2. If we write Nickel (II), it means Nickel with a charge of +2.
If we don't write the II, no one will know what charge Nickel actually is.
So, we write Nickel (II) Chloride.
Nickel gives off two electrons and Chlorine is only able to recieve one.
So, introduce another atom of Chlorine.
One atom of Nickel can give off two electrons and both atoms of Chlorine will recieve one each.
Since there is one atom of Nickel and two of Chlorine, we write NiCl2.Rate this question:

Boron has a charge of +3 and Nitrogen has a charge of -3. What is the chemical compound name and formula?
- A.
Boron Nitrogen and BN
- B.
Uniboron Uninitrogen and BN
- C.
Boron Nitride and B3N3
- D.
Boron Nitride and BN
Correct Answer
D. Boron Nitride and BNExplanation
Boron gives off 3 electrons and Nitrogen receives 3. It all balances out and you only need one atom of each.
Therefore the formula is BN.
The name is Boron Nitride because the metal comes first, nonmetal comes second, and the nonmetal always ends in -IDE.Rate this question:

Mercury (II) (Hg) has a charge of +2. Oxygen (O) has a charge of -2. What is the chemical compound name and formula?
- A.
Mercury (II) Oxide, HgO
- B.
Mercury Oxide, HgO
- C.
Mercury (II) Oxide, Hg2O
- D.
Mercury Oxygen, Hg2O
Correct Answer
A. Mercury (II) Oxide, HgOExplanation
Mercury (II) gives off 2 electron and Oxygen receives 2. It all balances out and you only need one atom of each. So the formula is HgO.
Mercury is one of the elements that doesn't have only charge, but many different possible charges.
The roman numeral II means 2. If we write Mercury (II), it means Mercury with a charge of +2.
If we don't write the II, no one will know what charge Mercury actually is.
So, we write Mercury (II) Oxide.Rate this question:

Why are ionic compounds brittle?
- A.
Because they're solids.
- B.
Because when something hits it, a layer of ions is pushed so that they are next to ions of the same charge. They are repulsed by each other and break.
- C.
Because they're not strong bonds.
- D.
Because when something hits it, a layer of ions is pushed so that they are next to ions of the same charge. They are attracted to each other and break.
Correct Answer
B. Because when something hits it, a layer of ions is pushed so that they are next to ions of the same charge. They are repulsed by each other and break.Explanation
Ionic compounds are brittle because when something hits them, a layer of ions is pushed so that they are next to ions of the same charge. Since ions of the same charge repel each other, this repulsion causes the lattice structure of the ionic compound to break, resulting in brittleness.Rate this question:
