select the correct answer. which statement correctly describes metallic bonds? a. they form when certain atoms lose electrons and other atoms gain electrons. b. they involve an attraction between anions and cations. c. they always involve both a metal and a nonmetal. d. they can only form between atoms of the same element. e. they form because electrons can move freely between atoms.

Answer

Brief Explanations:

Metallic bonds occur due to a sea - of - electrons model where electrons are delocalized and can move freely between metal atoms. Option A describes ionic bonds (electron transfer). Option B is also about ionic bonds (attraction between anions and cations). Option C is incorrect as metallic bonds are between metal atoms. Option D is wrong as alloys (mixtures of metals) show metallic bonds between different metal atoms. Option E correctly describes the nature of metallic bonds with free - moving electrons.

Answer:

E. They form because electrons can move freely between atoms.
