Difference of Chirality of the Electron Between Enantiomers of H$$_$$X$$_$$

The integrated chirality density of H\(_2\)X\(_2\) molecules is studied in viewpoints of the internal torque for the electron spin. Since the chirality density is proportional to the zeta potential, which is the potential of the zeta force, one of the torque for the electron spin, the distribution of the chirality density affects the distribution of the internal torque in molecules. It is seen that the integrated chirality density is larger for the larger atomic number. It is found that the integrated chirality density of H\(_2\)Te\(_2\) has the same sign as the parity-violating energy, while those of H\(_2\)O\(_2\) and H\(_2\)S\(_2\) are opposite to the sign of the parity-violating energy, and the dependence of the integrated chirality density of H\(_2\)Se\(_2\) on dihedral angle is significantly different from that of the parity-violating energy.
