Verified step by step guidance

Understand the nature of metallic bonding: In metallic bonding, atoms in a metal lattice share a 'sea' of delocalized electrons. These electrons are not bound to any specific atom and can move freely throughout the metal structure.

Identify the role of electrons in metallic bonding: The delocalized electrons are responsible for the conductivity and malleability of metals. They allow metals to conduct electricity and heat efficiently.

Consider the mobility of subatomic particles: In the context of metallic bonding, the electrons are the only subatomic particles that are free to move. Protons and neutrons are located in the nucleus and are not mobile.

Evaluate the options given: Protons and neutrons are part of the atomic nucleus and do not participate in the bonding process in metals. Quarks are subcomponents of protons and neutrons and are not involved in chemical bonding.

Conclude that electrons are the mobile subatomic particles in metallic bonding, as they form the 'sea' of electrons that allows for the unique properties of metals.
