Are Atoms Smaller Than Molecules

Tutorial on Chemical Bonding, Part 8 of 10 (Molecular orbitals) As two H nuclei move toward each other, the 1s atomic orbitals of the isolated atoms gradually merge into a new molecular orbital in which the greatest electron density falls between the two nuclei. Since this is just the location in which electrons can exert the most attractive force on the two nuclei simultaneously, this.

After the debate, looking more deeply into the theories of Penrose on quantum physics and consciousness, I have had the pleasure of getting

Although the hybrid orbital approach has proven very powerful (especially in organic chemistry), it does have its limitations. For example, it predicts that both H 2 O and H 2 S will be tetrahedrally coordinated bent molecules with bond angles slightly smaller than the tetrahedral angle of 109.5° owing to greater repulsion by the nonbonding pair. This description fits water (104.5°) quite.
