Question

How do metallic bonds share electrons?

Answer 1

Hint: Metals are a class of elements known for their generally high thermal and electrical conductivity which is an outcome of what happens inside their structure, they are composed of a sea of loosely bound electrons that are never localized on one atom.

Complete answer:
When we talk about what differentiates metals from other elements the first point that should come in our mind is their bulk structure. Due to shielding effect in outermost orbitals we find the presence of loosely bound electrons in the outermost orbitals. The presence of loosely bound electrons means that they can readily move from one atom to atom without spending much energy during the motion.

The above points were integrated into one theory leading to scientists proposing the kernel theory which states that metal nuclei in a metal are relatively stationary at their position and are surrounded by a sea of electrons which are free to move throughout the metal thus metallic bonds are comprised of electron sharing that occurs at a bulk level wherein electrons of every metal atom are shared by all the atoms present in the bulk.

Thus metallic bonds basically consist of overlapping outermost s and p orbitals of metals in which electrons move freely throughout the metal.

Note: The fact that whether or not are we able to answer the question given above comes down to simple knowledge of how the metal atoms interact and how are electrons bound to their respective atoms, knowing these basic concepts we can easily answer the question asked above.
