How many electrons does an atom need to fill its valence shell?
- A.
2
- B.
4
- C.
6
- D.
8
- E.
10
Correct Answer
D. 8Explanation
Atoms need 8 electrons to fill their valence shell. The valence shell is the outermost shell of an atom, and it can hold a maximum of 8 electrons. This is known as the octet rule, which states that atoms tend to gain, lose, or share electrons in order to achieve a stable configuration with 8 electrons in their valence shell. By filling their valence shell, atoms can achieve a more stable and lower energy state.Rate this question:

Nonmetals tend to gain electrons, forming negatively charged ions called _______.
Correct Answer
anionsExplanation
Nonmetals have a higher electronegativity compared to metals, which means they have a greater tendency to attract and gain electrons. When nonmetals gain electrons, they form negatively charged ions called anions. Anions have a greater number of electrons than protons, resulting in a negative charge. This allows nonmetals to achieve a stable electron configuration similar to that of noble gases, which makes them more stable and less reactive.Rate this question:
- 3.
Metals tend to lose electrons, forming positively charged ions called _______.
Correct Answer
cationsExplanation
Metals have a tendency to lose electrons, resulting in the formation of positively charged ions. These ions are called cations.Rate this question:

Ionic bonds involve transfer of electrons, but covalent bonds involve ______ of electrons.
Correct Answer
sharingExplanation
Covalent bonds involve the sharing of electrons. In a covalent bond, two atoms share one or more pairs of electrons in order to achieve a stable electron configuration. This sharing of electrons allows both atoms to fill their outermost energy levels and form a more stable molecule. Unlike ionic bonds, where electrons are completely transferred from one atom to another, covalent bonds involve a more equal sharing of electrons between atoms.Rate this question:
- 5.
The octet rule states that:
- A.
Atoms will lose, gain or share electrons to obtain a full valence shell
- B.
Bonding is unlikely to occur between oppositely charged ions.
- C.
A single covalent bond involves two pairs of shared electrons.
- D.
A covalent bond results between two oppositely charged ions.
- E.
Halogens often bond with alkaline earth metals.
Correct Answer
A. Atoms will lose, gain or share electrons to obtain a full valence shellExplanation
The octet rule states that atoms will lose, gain, or share electrons to obtain a full valence shell. This means that atoms tend to have a stable configuration by having 8 electrons in their outermost energy level. In order to achieve this, atoms can either give away or gain electrons to fill their valence shell, or they can share electrons with other atoms through covalent bonding. This rule helps explain the formation of chemical bonds and the stability of atoms.Rate this question:

In Lewis Dot Structure, the dots represent _______ electrons.
Correct Answer
valenceExplanation
In Lewis Dot Structure, the dots represent valence electrons. Valence electrons are the electrons in the outermost energy level of an atom. They are responsible for the chemical properties and bonding behavior of an element. By representing them as dots in the Lewis Dot Structure, we can easily determine the number of valence electrons and predict the possible bonding patterns of atoms.Rate this question:

The charge that hold oppositely charged atoms together is called
- A.
Metallic bonds
- B.
Electrostatic force
- C.
Covalent bonds
- D.
Hund's rule
- E.
Pauli Exclusion Principle
Correct Answer
B. Electrostatic forceExplanation
The electrostatic force is the correct answer because it is the force of attraction between oppositely charged particles, such as electrons and protons. In the context of holding oppositely charged atoms together, this force is responsible for the formation of chemical bonds, whether they are metallic, covalent, or ionic. Metallic bonds involve the sharing of electrons between metal atoms, while covalent bonds involve the sharing of electrons between nonmetal atoms. Both of these types of bonds are held together by the electrostatic force of attraction between the positively charged atomic nuclei and the negatively charged electrons.Rate this question:

Two hydrogen atoms sharing one pair of electrons to fill their valence shells with two electrons each is called a ______ covalent bond.
Correct Answer
singleExplanation
When two hydrogen atoms share one pair of electrons, they form a single covalent bond. In this type of bond, each hydrogen atom contributes one electron to the shared pair, resulting in both atoms having a full valence shell with two electrons each. This sharing of electrons allows the atoms to achieve stability and form a strong bond between them.Rate this question:

In Lewis dot structure of two covalently bonded atoms, a line between a dot of each of two atoms represents
- A.
Electrostatic force
- B.
An ionic bond
- C.
A shared pair of electrons
- D.
The electron cloud
- E.
Valence electrons
Correct Answer
C. A shared pair of electronsExplanation
In the Lewis dot structure of two covalently bonded atoms, a line between a dot of each of two atoms represents a shared pair of electrons. Covalent bonds occur when atoms share electrons in order to achieve a stable electron configuration. The line in the Lewis dot structure represents the sharing of a pair of electrons between the two atoms, indicating the presence of a covalent bond.Rate this question:

A bond involving the sharing of three pairs of electrons, such as two atoms of covalently bonded nitrogen is called a _____ covalent bond.
Correct Answer
tripleExplanation
A bond involving the sharing of three pairs of electrons, such as two atoms of covalently bonded nitrogen, is called a triple covalent bond. In a triple covalent bond, three pairs of electrons are shared between the atoms, resulting in a strong bond. This type of bond is typically found in molecules with atoms that require a high number of electrons to achieve stability, such as nitrogen.Rate this question:
