Answer 1

The correct answer is:

(c) Metallic bond

Explanation:

Metallic bonds are considered non-directional in nature. In metallic bonding, metal atoms share a "sea" of free electrons that are not localized to specific atoms or directions. This allows metals to conduct electricity and have properties such as malleability and ductility. Since the bonding is not dependent on a specific direction, it is classified as non-directional.

• Covalent bonds are directional because the electrons are shared between specific atoms, creating a bond along a particular axis or direction.
• Ionic bonds are non-directional in the sense that the attraction between positively and negatively charged ions does not depend on the direction of the bonds, but the bonding itself tends to form a lattice structure, which does have directionality in the arrangement of ions.

Thus, among the given options, metallic bond is the correct answer for a non-directional bond.
