Which compound is composed of oppositely charged ions? a. ocl2 b. na2o c. nh3 d. scl2

The correct answer is Option B.

Explanation:

Compound having oppositely charged ions are considered as ionic compounds.

Ionic compounds are formed when complete transfer of electrons takes place between the atoms forming a bond. This bond is formed between a metal and a non-metal or a polyatomic cation and an non-metal or a metal and a polyatomic anion. For Example: etc..

Covalent compounds are formed when sharing of electrons takes place between the atoms forming a bond. This bond is formed between two non-metals. For Example: etc..

For the given options:

Option A:  

Oxygen and chlorine both are non-metals. Thus, it is forming a covalent compound.

Option B:  

Sodium is a metal and oxygen is a non-metal. Thus, it is forming an ionic compound and contain oppositely charged ions.

Option C:  

Nitrogen and hydrogen both are non-metals. Thus, it is forming a covalent compound.

Option D:  

Sulfur and chlorine both are non-metals. Thus, it is forming a covalent compound.

Hence, the correct answer is Option B.

a is the answer to this question
