Hello! I am working on some homework and came across this question, which completely confuses me for various reasons. Experimental evidence suggests that the nitrogen atom in ammonia, NH3, has four identical orbitals in the shape of a pyramid or tetrahedron. a). Draw an energy-level diagram to show the formation of these hybrid orbitals. (Hint: no electron promotion is required). b). Name the type of hybrid orbitals found in NH3. Of the four hybrid orbitals on the N atom, how many will take part in bonding? Explain.
