What occurs when a sodium ion (Na+) is attracted to a chloride ion (Cl-)?
A
They form a hydrogen bond.
B
They repel each other.
C
They form a covalent bond.
D
They form an ionic bond.
Verified step by step guidance1
Identify the nature of the ions involved: Sodium ion (Na+) is a positively charged cation, and chloride ion (Cl-) is a negatively charged anion.
Understand the concept of ionic bonds: Ionic bonds are formed when there is an electrostatic attraction between oppositely charged ions.
Recognize that sodium (Na) tends to lose one electron to achieve a stable electron configuration, becoming Na+, while chlorine (Cl) tends to gain one electron to achieve stability, becoming Cl-.
When Na+ and Cl- come into proximity, the opposite charges attract each other, leading to the formation of an ionic bond.
Conclude that the attraction between Na+ and Cl- results in the formation of an ionic compound, specifically sodium chloride (NaCl), which is a classic example of an ionic bond.
