Q-00002059

How does the loss of an electron by sodium and gain of an electron by chlorine lead to the formation of sodium chloride?

1

Sodium loses an electron to form a positive ion, while chlorine gains an electron to form a negative ion, resulting in the formation of sodium chloride

2

Sodium gains an electron to form a positive ion, while chlorine loses an electron to form a negative ion, resulting in the formation of sodium chloride

3

Sodium and chlorine both lose electrons to form positive ions, resulting in the formation of sodium chloride

4

Sodium and chlorine both gain electrons to form negative ions, resulting in the formation of sodium chloride

Answer and Solution

Answer

A. Sodium loses an electron to form a positive ion, while chlorine gains an electron to form a negative ion, resulting in the formation of sodium chloride

Solution:

In the formation of sodium chloride, sodium loses an electron to achieve a stable electronic configuration, forming a positive ion, while chlorine gains this electron to achieve stability, forming a negative ion, leading to the combination of the two ions to form sodium chloride.
