Question

Which is a characteristic of the electron sea model for metallic bonding

Molecular orbitals overlap to produce Bands

Electrons flow easily between metal nuclei

Atomic nuclei are arranged in an irregular pattern

Answer 1

According to the electron sea model for metallic bonding, in the sample of metal atom all the atoms contribute their valence electrons which form a delocalized “sea” of electrons. The arrangement of metal ions is in an orderly array with this mobile sea of electrons. The metal is held together due to the attraction between sea of electrons and cations.

Hence, electrons flow easily between metal nuclei is a characteristic of the electron sea model for metallic bonding.

Answer 2

the bonding in metals is sometimes decribed as a "Sea of delocalise electrons" this is because the metal atoms are all regularly arranged and are surrounded in free delocalised electrons that can Flow easily between the metal nucli so therefore the answer is the second answer
