When one atom of hydrogen (H) combines with one atom of chlorine (Cl), a polar covalent bond forms between the H and the more electronegative Cl, resulting in a molecule of HCl. Which of the following describes the arrangement of valence electrons in a bond between H and Cl?

The valence electrons are shared equally between H and Cl.

The valence electrons spend more time around the atom of H.

The valence electrons spend more time around the atom of Cl.

The valence electrons are given up by the H and gained by the Cl.

Oooo, yahhhh. So, yeah, HCl is a polar substance. This is because chlorine is more electronegative than the hydrogen. Chlorine is like the 'negative side' of the molecule. Therefore, the electron density is closer to the chlorine. Therefore, the valence electrons spend more time around the chlorine.
