1. The problem statement, all variables and given/known data Experimental evidence suggests that the nitrogen atom in ammonia, NH3 , has four orbitals in the shape of a pyramid or tetrahedron. Draw an energy-level diagram to show the formation of these orbitals. (Hint: No electron promotion is required.) 2. Relevant equations 3. The attempt at a solution First answer: http://i979.photobucket.com/albums/ae277/clubangel777/Science Homework/SCH4U-BQuestion6ab.jpg Second answer: http://i979.photobucket.com/albums/ae277/clubangel777/Science Homework/HybridAmmoniaNitrogen.jpg My sister came up with the first answer, but the teacher emailed her the second answer. There is confusion because she thinks Nitrogen should have 7 Electrons and the teacher said there are 6 Electrons.
