HYDROGEN Molecule, H2 #2 Sectioned Van der Waals Surface

The covalent hydrogen radii are shown as green spheres just touching, and the Van der Waals surface (the effective boundary of the molecule) is a solid that's been cut away to reveal the green balls inside. The H2 molecule sits on a semi-reflective surface. Green hydrogen (produced without generating net greenhouse emissions) should be a major player in preventing global warming.
