the electrons in the valence shell of many atoms do not leave the atom because the protons in the nucleus attract the electrons. however, in metals,\no electrons can flow from one atom to another.\no protons can flow from one atom to another.\no protons attract protons of other atoms.\no electrons attract electrons of other atoms.

Answer

Brief Explanations:

In metals, there is a sea - of - electrons model. Valence electrons are delocalized and can flow freely from one atom to another, which is responsible for properties like electrical conductivity. Protons are in the nucleus and do not move between atoms. Protons attract electrons, not other protons in this context, and electrons repel other electrons due to like - charge.

Answer:

electrons can flow from one atom to another.
