Answer

Brief Explanations:

In metals, valence electrons are not confined to a single atom's orbital. Instead, they are shared among multiple atoms. This is known as delocalization.

  • Option 1: In a metal, valence electrons are in shared orbitals and can move between atoms. This is the correct description of delocalized electrons.
  • Option 2: Valence electrons are in outer orbitals. Moving to inner orbitals is not what delocalization means.
  • Option 3: Valence electrons start in outer orbitals. Moving from inner to outer orbitals is not relevant to delocalization.
  • Option 4: Electrons do not move out of the metal into the air. They remain within the metal's structure.

Answer:

The valence electrons move between atoms in shared orbitals.
