Question

Which compound is composed of oppositely charged ions? A. OCl2 B. Na2O C. NH3 D. SCl2

Answer 1

Answer: 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: $NaCl,NH_4Cl,BaSO_4$ 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: $H_2O,SO_2$ etc..

For the given options:

Option A:  $OCl_2$

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

Option B:  $Na_2O$

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

Option C:  $NH_3$

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

Option D:  $SCl_2$

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

Hence, the correct answer is Option B.

Answer 2

It would be B, so yeah hope that helps ya ;)
