Question 22

Ionic bonds involve atoms gaining or losing electrons.

Ionic bonds are formed when one atom transfers electrons to another, resulting in the formation of charged ions. This transfer occurs due to differences in electronegativity between the atoms involved.

A) Ionic

This option is correct because ionic bonds specifically involve the transfer of electrons from one atom to another. When an atom loses electrons, it becomes positively charged, while the atom that gains those electrons becomes negatively charged, leading to the formation of ionic compounds.

B) Covalent

Covalent bonds are not characterized by the transfer of electrons, but rather by the sharing of electrons between atoms. This means that atoms in a covalent bond do not gain or lose electrons, making this option incorrect.

C) Both

This option is incorrect because while ionic bonds involve the transfer of electrons, covalent bonds do not. Therefore, stating that both types of bonds involve the gaining or losing of electrons is misleading and inaccurate.

D) Neither

This option is also incorrect since ionic bonds do involve the gaining or losing of electrons. Thus, claiming that neither type of bond involves this process contradicts the definition of ionic bonding.

Conclusion

Ionic bonds are uniquely defined by the transfer of electrons between atoms, leading to the formation of ions. All other options fail to accurately describe the behavior of atoms in ionic bonding, making A the definitive correct answer.
