WebMy major contributions have been in two areas: 1. Structure and dynamics of organic films on water surface 2. Structure and dynamics of fluids confined within nanometric dimensions In 1, I have found the effect of specific metal ions on these films giving rise to (a) metal-ion superlattices underneath these films and (b) the stable 'bi-molecular film' on water … WebA water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other. thomas fyrstWeb9 apr. 2024 · Ionic bonding is the electrostatic forces of attraction between positively-charged ions and negatively-charged ions.
