What chemical phenomenon accounts for the elasticity seen in solids?

covalent bond
hydrogen bond
ionic bond
all of the above.

Your answer is hydrogen bonds.

The correct answer is:

covalent bond.

Covalent bonds between atoms are responsible for the elasticity observed in solids. These bonds involve the sharing of electron pairs between atoms, resulting in a strong and stable connection. When a solid is subjected to external forces, such as stretching or compressing, the covalent bonds can temporarily deform and then return to their original configuration once the force is removed. This behavior gives solids their elasticity.

The chemical phenomenon that accounts for the elasticity seen in solids is the covalent bond.

To understand why, let's break it down. Elasticity refers to the ability of a material to deform under stress and return to its original shape once the stress is removed. In solids, this is primarily governed by the arrangement and strength of the chemical bonds between atoms.

In a covalent bond, atoms share electrons to form a stable bond. These shared electrons create a strong connection between the atoms, making the bond relatively rigid. When a solid is subjected to a stress or deformation, the covalent bonds stretch or compress, allowing the material to temporarily change its shape. Once the stress is removed, the covalent bonds return to their original state, causing the material to regain its original shape.

On the other hand, hydrogen bonds and ionic bonds are not primarily responsible for the elasticity seen in solids. Hydrogen bonds are relatively weak interactions between molecules, not within a single molecule or solid structure. Ionic bonds are strong and they do play a role in the physical properties of solids, but they are not directly responsible for the elasticity.

Therefore, the correct answer is "covalent bond."

This is not an easy question, if you examine common flexible polymers, especially thermoplastic polymers (hydrogen intermolecular bonds) and polymer blends (molecules incompatable for bonding, so create movable domains of molecules).

But, in general, at least classically, long chain carbon covalent bonds of molecules (especially those that form spiral molecules) are "elastic" as we know them.
