Why methane is a tetrahedron
physical
Four bonding pairs and no lone pairs around a central atom push apart into a tetrahedron with 109.47° angles — the shape of methane, and of carbon's whole architecture. Worked & sealed by the engine — 4 bonds, 0 lone pairs → tetrahedral, 109.47°. [HOLDS; open the seal to re-check.]
