Choose the correct number of electrons in the Lewis structure for NH₃.

Question

Quizplus · Accepted Answer

The Lewis structure for NH₃ shows the presence of N, H, S, and B atoms. These atoms will contribute their valence electrons to form bonds and/or fill lone pairs. Counting up the total valence electrons present in the molecule: N = 5 H = 1 x 1 = 1 S = 6 B = 3 Total = 5 + 1 + 6 + 3 = 15 A single bond contains 2 electrons, and each atom in the molecule requires at least one electron to fill its valence shell. Therefore, the minimum number of electrons required for the Lewis structure is 15/2 = 7.5 or 8. Thus, the correct answer is D with eight electrons in the Lewis structure.
