A molecule has a characteristic size and shape, which are key to its function in the living cell. A molecule consisting of two atoms, such as H2 or O2, is always linear, but most molecules with more than two atoms have more complicated shapes. These shapes are determined by the positions of the atoms’ orbitals. When an atom forms covalent bonds, the orbitals in its valence shell undergo rearrangement.

Hybridization of orbitals. The single s and three p orbitals of a valence shell involved in covalent bonding combine to form four teardrop-shaped hybrid orbitals. These orbitals extend to the four corners of an imaginary tetrahedron.

Molecular-shape models. Three models representing molecular
shape are shown for water and methane. The positions of the
hybrid orbitals determine the shapes of the molecules.
