Covalent Vs. Ionic Bonding
Easy quiz about Covalent and ionic bonding.
Questions and Answers
- 1.
An ionic bond is when two atoms?
- A.
Share their electrons
- B.
Both lose electrons to for a full shelf
- C.
One loses an electron and one gains an electron
- D.
Both gain electrons till the have a full shelf
Correct Answer
C. One loses an electron and one gains an electronExplanation
In an ionic bond, one atom loses an electron while the other atom gains an electron. This occurs because one atom has a lower electronegativity and tends to lose electrons, while the other atom has a higher electronegativity and tends to gain electrons. This transfer of electrons creates charged particles called ions, which are held together by electrostatic forces to form the ionic bond.Rate this question:

Octet Law states that atoms tend to _____,______ or _______ electrons.
Correct Answer
Gain, lose or shareExplanation
The Octet Law is a fundamental principle in chemistry that states atoms tend to either gain, lose, or share electrons. This is because atoms strive to achieve a stable electron configuration, typically by having a full outermost energy level with eight electrons, known as an octet. By gaining or losing electrons, atoms can achieve this stable configuration. Alternatively, atoms can also share electrons with other atoms through covalent bonding to achieve a stable electron configuration.Rate this question:

Covalent bonds are when two atoms?
- A.
Share an electron to create a full shelf
- B.
Gain an electron to create a full shelf
- C.
Lose an electron to create a full shelf
Correct Answer
A. Share an electron to create a full shelfExplanation
Covalent bonds occur when two atoms share electrons to achieve a stable electron configuration. By sharing electrons, both atoms can fill their outermost electron shells, resulting in a full shelf of electrons. This sharing of electrons allows the atoms to form a strong bond and achieve a more stable state.Rate this question:

Lewis dot shows?
- A.
The total number of electrons
- B.
Total number of protons
- C.
Total number of neutrons
- D.
Number of electrons in highest energy shelf
Correct Answer
D. Number of electrons in highest energy shelfExplanation
The Lewis dot structure is a representation of an atom's valence electrons, which are the electrons in the highest energy level or outermost shell. These valence electrons are the ones involved in chemical bonding and determining the atom's reactivity. Therefore, the number of electrons in the highest energy shelf is shown in the Lewis dot structure.Rate this question:

A covalent bond that is a triple bond contains this amount of shared electrons
- A.
2
- B.
6
- C.
4
- D.
8
Correct Answer
B. 6Explanation
A triple bond consists of three pairs of shared electrons. Each pair of electrons consists of two electrons, so three pairs of electrons would contain a total of six shared electrons.Rate this question:

The most common covalent compound is
- A.
Water
- B.
Hydrogen
- C.
Ammonia
- D.
Sodium chloride
Correct Answer
A. WaterExplanation
Water is the most common covalent compound because it is composed of two hydrogen atoms bonded to one oxygen atom through covalent bonds. Covalent compounds are formed when atoms share electrons, and water is a prime example of this type of compound. It is abundant on Earth and essential for life, making it the most common covalent compound.Rate this question:

A full shelf contains ?
- A.
3 electrons
- B.
9 electrons
- C.
12 electrons
- D.
8 electrons
Correct Answer
D. 8 electronsExplanation
A full shelf contains 8 electrons because in the context of electron configuration, each energy level or shell can hold a maximum number of electrons. The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and so on. Since the question does not specify the energy level of the shelf, it can be assumed that it refers to the second energy level, which can hold a maximum of 8 electrons.Rate this question:

The higher the bond
- A.
The further the nuclues are
- B.
No change
- C.
The close the nucleus are
Correct Answer
C. The close the nucleus areExplanation
The correct answer suggests that the closer the nucleus is, the higher the bond. This explanation is based on the concept of atomic bonding, specifically in relation to the distance between the atomic nucleus and the electrons. When the nucleus is closer to the electrons, the attractive force between them is stronger, resulting in a higher bond. Conversely, when the nucleus is further away, the attractive force is weaker, leading to a lower bond. Therefore, the statement implies a direct relationship between the proximity of the nucleus and the strength of the bond.Rate this question:

The most highly active elements to bonding are
- A.
The transitional metals
- B.
The noble gases
- C.
The alkali metals
Correct Answer
C. The alkali metalsExplanation
The alkali metals are the most highly active elements when it comes to bonding. This is because they have only one electron in their outermost energy level, making them highly reactive and eager to lose that electron to achieve a stable electron configuration. This tendency to lose an electron makes them excellent at forming bonds with other elements, especially nonmetals, to achieve a stable octet. The transitional metals and noble gases, on the other hand, are generally less reactive and have different bonding characteristics.Rate this question:

True or false: Covalent bonding is the same as ionic bonding.________
Correct Answer
FalseExplanation
Covalent bonding and ionic bonding are not the same. Covalent bonding occurs when two atoms share electrons, resulting in a stable molecule. Ionic bonding, on the other hand, involves the transfer of electrons from one atom to another, creating charged ions that are attracted to each other. Therefore, the statement that covalent bonding is the same as ionic bonding is false.Rate this question:
