The balls are colored: black represents carbon (C), red represents oxygen (O), blue represents nitrogen (N), and white represents hydrogen (H) (H). Each ball is drilled with as many holes as its valence (C: 4; N: 3; O: 2; H: 1), oriented towards the tetrahedron's vertices. Single bonds are depicted by grey rods that are (relatively) stiff.
