In forming ammonia, nitrogen uses:
A. sp orbitals.
B. sp1 orbitals.
C. sp2 orbitals.
D. sp3 orbitals.
Ammonia has the formula NH3. Nitrogen uses four sp3 orbitals in forming this molecule; they are directed toward the corners of a regular tetrahedron, with one orbital containing a pair of electrons. The other three each contain a single electron.
