Chemical Bonding: Ionic Bonding
.webp "Chemical Bonding: Ionic Bonding - Quiz")
Take A Real Quiz: 50 points- You'd better try hard. ��The combining of elements to form different substances is called chemical bonding. The world around you is made up of thousands and thousands of different compounds formed from chemical bonds. There are three types of chemical bonds: ionic bonding, covalent bonding and metallic bonding. This quiz will focus on ionic bonding. Use your knowledge of ions and ionic bonding to answer the following questions.
Questions and Answers
- 1.
Atoms are electrically neutral; that is they do not have a charge.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Atoms are composed of protons, neutrons, and electrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. The positive charge of the protons is balanced by the negative charge of the electrons, resulting in an overall neutral charge for the atom. Therefore, atoms do not have a charge.Rate this question:

- 2.
Electrons have what kind of charge?
- A.
Positive
- B.
Negative
- C.
Neutral
Correct Answer
B. NegativeExplanation
Electrons have a negative charge. This is because electrons are subatomic particles that orbit around the nucleus of an atom, and they carry a negative electrical charge. The negative charge of electrons is equal in magnitude to the positive charge of protons, which are found in the nucleus of an atom. This balance of positive and negative charges allows atoms to remain electrically neutral overall.Rate this question:

What is the name given to the outermost electron(s)?
- A.
Outside electrons
- B.
Plutonium electrons
- C.
Valence electrons
Correct Answer
C. Valence electronsExplanation
Valence electrons are the outermost electrons in an atom that participate in chemical reactions and determine the atom's reactivity. These electrons are located in the outermost energy level or shell of an atom and are involved in forming chemical bonds with other atoms. The term "valence" refers to the combining capacity of an atom, and valence electrons play a crucial role in the formation of chemical compounds.Rate this question:

When an electron is added to or removed from an atom, the atom becomes a(n) ________.
- A.
Ion
- B.
Bond
- C.
Nothing; it stays an atom
Correct Answer
A. IonExplanation
When an electron is added to or removed from an atom, the atom becomes an ion. This is because the addition or removal of an electron results in a change in the atom's overall charge. If an electron is added, the atom becomes negatively charged and is called an anion. If an electron is removed, the atom becomes positively charged and is called a cation. In both cases, the atom has gained or lost an electron, resulting in the formation of an ion.Rate this question:

- 5.
The process of removing or adding electrons is called __________.
- A.
Work
- B.
Ionization
- C.
Electrification
Correct Answer
B. IonizationExplanation
Ionization is the process of removing or adding electrons. When an atom or molecule gains or loses electrons, it becomes charged and is called an ion. This process can occur through various means such as heating, chemical reactions, or exposure to radiation. Ionization plays a crucial role in many scientific and technological processes, including the creation of plasma, the operation of ion engines, and the formation of ions in the Earth's atmosphere.Rate this question:

Positively charged ions, called ____________, result from loss of electrons.
- A.
Cations
- B.
Anions
Correct Answer
A. CationsExplanation
Positively charged ions, called cations, are formed when an atom loses electrons. This loss of electrons creates an imbalance between the number of protons and electrons, resulting in a net positive charge. Anions, on the other hand, are negatively charged ions that are formed when an atom gains electrons. Therefore, the correct answer is cations.Rate this question:
-
- 7.
Negatively charged ions, called ____________, result from gain of electrons.
- A.
Cations
- B.
Anions
Correct Answer
B. AnionsExplanation
Anions are negatively charged ions that result from the gain of electrons. When an atom gains one or more electrons, it becomes negatively charged and forms an anion. This occurs because the atom now has more electrons than protons, giving it a net negative charge. Cations, on the other hand, are positively charged ions that result from the loss of electrons. Therefore, the correct answer is anions.Rate this question:
-
- 8.
An _______ bond forms when a cation transfers its extra electron to an anion who needs it.
- A.
Metallic
- B.
Covalent
- C.
Ionic
Correct Answer
C. IonicExplanation
An ionic bond forms when a cation, which is a positively charged ion, transfers its extra electron to an anion, which is a negatively charged ion, who needs it. This transfer of electrons creates a strong electrostatic attraction between the cation and the anion, resulting in the formation of an ionic bond. Ionic bonds typically occur between metals and nonmetals, where the metal loses electrons to form a cation and the nonmetal gains electrons to form an anion. This transfer of electrons allows both ions to achieve a stable electron configuration and results in the formation of a compound with a neutral overall charge.Rate this question:

- 9.
Ions of opposite charge __________ each other easily, so they form a specific pattern called a crystal lattice.
- A.
Repel
- B.
Attract
Correct Answer
B. AttractExplanation
Ions of opposite charge attract each other easily, causing them to form a specific pattern known as a crystal lattice. This attraction is due to the electrostatic force between the positive and negative charges of the ions. The opposite charges attract each other, resulting in the formation of a stable and organized arrangement.Rate this question:
-
- 10.
Ionic bonds always form between metals and ___________.
- A.
Nonmetals
- B.
Metals
- C.
Metalloids
Correct Answer
A. NonmetalsExplanation
Ionic bonds occur between a metal and a nonmetal. In an ionic bond, the metal atom loses electrons to become a positively charged ion, while the nonmetal atom gains those electrons to become a negatively charged ion. This electrostatic attraction between the oppositely charged ions forms the ionic bond. Therefore, the correct answer is nonmetals.Rate this question:
