Question 11

An ionic bond is formed when an electron is transferred from one atom to another.

When an electron is transferred from one atom to another, it results in the formation of an ionic bond. This type of bond occurs between atoms with significantly different electronegativities, leading to the creation of charged ions.

A) Ionic bond

This option is correct because an ionic bond is specifically characterized by the transfer of electrons from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other due to electrostatic forces.

B) Covalent bond

A covalent bond is formed when two atoms share electrons rather than transferring them. This option is incorrect in the context of the question, as it does not involve the transfer of electrons, which is the defining characteristic of ionic bonds.

C) Elemental bond

This term is not commonly used in chemistry to describe a specific type of bond. It is unclear and thus incorrect in the context of the question. The formation of bonds between atoms does not typically fall under this classification.

D) Metallic bond

A metallic bond involves the sharing of free electrons among a lattice of metal atoms, rather than the transfer of electrons between different atoms. Therefore, this option is incorrect as it does not pertain to the transfer of electrons that defines ionic bonding.

Conclusion

An ionic bond is definitively the correct answer because it specifically describes the transfer of electrons between atoms, leading to the formation of charged ions. All other options either misrepresent the nature of bonds or do not apply to the scenario of electron transfer, emphasizing the unique properties of ionic bonds in atomic interactions.
