When an atom loses or gains electrons, it becomes...
- A.
An electrolyte
- B.
A bond
- C.
A compound
- D.
An ion
Correct Answer
D. An ionExplanation
When an atom loses or gains electrons, it becomes an ion. An ion is formed when an atom gains or loses electrons, resulting in a positive or negative charge. This process occurs during chemical reactions, where atoms either donate or accept electrons to achieve a stable electron configuration. The gain or loss of electrons creates an imbalance between the number of protons and electrons, leading to the formation of an ion. Ions play a crucial role in various biological and chemical processes, as they can interact with other ions or molecules to form compounds and participate in electrical conductivity.Rate this question:

Ionic bonding usually occurs between what type of atoms?
- A.
Metal and metal
- B.
Non-metal and non-metal
- C.
Metal and non-metal
- D.
Metal and noble gas
Correct Answer
C. Metal and non-metalExplanation
Ionic bonding usually occurs between metal and non-metal atoms. In an ionic bond, one atom transfers electrons to another atom, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions). Metals tend to lose electrons and form cations, while non-metals tend to gain electrons and form anions. The attraction between the oppositely charged ions leads to the formation of an ionic bond. This type of bonding is commonly observed in compounds like sodium chloride (NaCl), where sodium (metal) donates an electron to chlorine (non-metal).Rate this question:

When a non-metal atom becomes a non-metal ion...
- A.
It becomes negatively charged
- B.
It becomes neutrally charged
- C.
It doesn't change its charge
- D.
It becomes positively charged
Correct Answer
A. It becomes negatively chargedExplanation
When a non-metal atom becomes a non-metal ion, it gains electrons from other atoms, resulting in an increase in the number of negatively charged particles (electrons) compared to the number of positively charged particles (protons). This excess of electrons gives the ion a negative charge.Rate this question:

How many ionic bonds are formed when magnesium combines with chlorine?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
B. 2Explanation
When magnesium combines with chlorine, it forms an ionic compound called magnesium chloride. Magnesium has a valence of 2, meaning it can lose 2 electrons, while chlorine has a valence of 1, meaning it can gain 1 electron. To achieve stability, magnesium loses 2 electrons and chlorine gains 1 electron, resulting in the formation of 2 ionic bonds between one magnesium atom and two chlorine atoms. Therefore, the correct answer is 2.Rate this question:

How are electrons involved in ionic bonding?
- A.
Electrons are shared between the atoms involved
- B.
Electrons are lost or gained by the atoms
- C.
Electrons are taken into an inner shell of one of the atoms
- D.
Electrons are all moved to the outer shell of the atoms
Correct Answer
B. Electrons are lost or gained by the atomsExplanation
In ionic bonding, electrons are transferred between atoms. One atom loses electrons and becomes positively charged (called a cation), while another atom gains those electrons and becomes negatively charged (called an anion). This transfer of electrons allows the atoms to achieve a stable electron configuration and form an ionic bond.Rate this question:

Correct Answer
A. 1Explanation
When sodium bonds with chlorine, they form an ionic bond. In this type of bond, sodium loses one electron to become a positively charged ion (Na+), while chlorine gains one electron to become a negatively charged ion (Cl-). The opposite charges attract each other, resulting in the formation of a single ionic bond between sodium and chlorine. Therefore, the correct answer is 1.Rate this question:

What happens to the electron configuration of the atoms?
- A.
The electron configuration becomes that of a noble gas
- B.
The electron configuration always loses one electron
- C.
The electron configuration always gains an electron
- D.
The electron configuration stays the same
Correct Answer
A. The electron configuration becomes that of a noble gasExplanation
When the electron configuration of an atom becomes that of a noble gas, it means that the atom has achieved a stable electron configuration. Noble gases have a full outer electron shell, which makes them highly stable and unreactive. By gaining or losing electrons, atoms can achieve a stable electron configuration similar to that of a noble gas. This stability is desirable because it minimizes the atom's tendency to react with other atoms and form chemical bonds. Therefore, the correct answer is that the electron configuration becomes that of a noble gas.Rate this question:

Pick the correct combination for the properties of ionic compounds.
- A.
Conduct electricity Low boiling point
- B.
Do not conduct electricity when dissolved or molten High melting point
- C.
Conduct electricity when dissolved or molten High melting point
- D.
Do not conduct electricity Low melting point
Correct Answer
C. Conduct electricity when dissolved or molten High melting pointExplanation
Ionic compounds are composed of positive and negative ions held together by electrostatic forces. When dissolved or molten, the ions are free to move and conduct electricity. This is because the movement of ions allows for the flow of electric current. Additionally, ionic compounds have high melting points due to the strong electrostatic forces between the ions, which require a significant amount of energy to break. Therefore, the correct combination for the properties of ionic compounds is that they conduct electricity when dissolved or molten and have a high melting point.Rate this question:
