Which statement best describes the valence electrons in metallic bonds?
A
They are tightly bound to individual atoms and do not move.
B
They are delocalized and move freely throughout the metal lattice.
C
They are transferred completely from one atom to another.
D
They are shared in pairs between two specific atoms.
Verified step by step guidance1
Understand that metallic bonds involve the interaction between metal atoms and their valence electrons.
Recall that in metallic bonding, valence electrons are not localized to any single atom but instead form a 'sea of electrons' that surrounds the metal cations.
Recognize that these valence electrons are free to move throughout the entire metal lattice, which explains properties like electrical conductivity and malleability in metals.
Contrast this with other types of bonding: in ionic bonds, electrons are transferred; in covalent bonds, electrons are shared between specific atoms; and in atomic orbitals without bonding, electrons are tightly bound to individual atoms.
Conclude that the best description of valence electrons in metallic bonds is that they are delocalized and move freely throughout the metal lattice.
