What change into velocity

Would you expect the h atoms to remain bonded to each other, or would the molecule fall apart?

Conductivity in a metal results from the metal atoms having (1) high electronegativity (2) high ionization energy (3) highly mobile protons in the nucleus (4) highly mobile electrons in the valence shell

All atoms are neutral. explain the basis of this fact
