A. valence electrons drift freely around the metal anions
Explicación
## Step 1The electron sea model is a theoretical model used to explain the properties of metals. According to this model, the valence electrons of a metal are not confined to a specific atom, but rather they are free to move around the metal lattice. This is because the valence electrons are not tightly bound to any particular atom and can move freely throughout the metal.## Step 2The electron sea model also suggests that the metal cations, which are positively charged ions, are embedded in a sea of delocalized electrons. This sea of electrons is what gives metals their characteristic properties, such as electrical conductivity and malleability.## Step 3The electron sea model does not suggest that the valence electrons are anchored to specific metal anions or cations. This is because the valence electrons are not confined to a specific atom but can move freely throughout the metal lattice.
