Option 1. is the right answer. Because in 1. the wavefunction is symmetric (changing the position of r1 and r2 doesn't change ) and symmetric configuration has less energy than antisymmetric (where changing the position of r1 and r2 gives - ). The reason is that the symmetric configuration is stable and leads to bonding while antisymmetric is unstable. Symmetric wavefunction maximizes the electric probability density between two protons and hence reducing the electrostatic repulsion among them.

SMA #8: Bohr and Schrödinger Models of Hydrogen Here we investigate the relationship between the Schrödinger and Bohr models of hydrogen-like atoms, following our work in class on both 9 1. Using the appropriate Schrödinger wavefunctions, compute the most probable electron-proton radii (i.e., distances) for 1s, 2p, and 3d states. Do these agree with the corresponding Bohr radii? Hint #1: Remember to maximize the "radial distribution function" P(r) = [rR(r)], i.e., to include the radial Jacobian factor (r2) in your...
