what is necessary for a metallic bond to form?\nthe atoms should be in close proximity.\nthe atoms should be far apart.\nthe electrons must be attracted to each other.\nthe nuclei must contain neutrons.
Answer
Brief Explanations:
Metallic bonds form when metal atoms are close - packed in a lattice. The delocalized electrons move freely among the positively charged metal ions. For this to occur, atoms need to be in close proximity. Atoms being far apart won't allow for the formation of the sea of electrons characteristic of metallic bonds. Electrons in metallic bonds are delocalized and not attracted to each other in the context of bond - formation. The presence of neutrons in the nuclei is not a requirement for metallic bond formation.
Answer:
The atoms should be in close proximity.
