In a polyatomic molecule, central atom solely determines the shape. For each of the following draw the Lewis dot structure and determine electronic geometry, molecular shape and bond angle. 4. Chemistry. 85% average accuracy. 45 seconds . No votes so far! Bond angle  is determined by connecting the two adjacent atoms with a central atom. CH4 (methane) is a molecule representative of tetrahedral bond angle geometry & is roughly 175mm (9") high when constructed from Unit model parts. CH4 has no lone pairs of Electrons on the central atom so the optimal molecular shape would be tetrahedral with bond angels of 109.5. The resulting shape is a regular tetrahedron with H-C-H angles of 109.5°. What do you observe for electronic, molecular geometry and bond angle? Lone pair on central atom is considered as electron cloud and repels the bond pair of electrons causing the bond angle to decrease. 68% average accuracy.
