Lewis structure
![Draw the Lewis structure of hydroxylamine. Start by drawing the overall structure of the molecule: Count the total valence electrons of the hydrogen (n_H, val = 1), nitrogen (n_N, val = 5), and oxygen (n_O, val = 6) atoms: 3 n_H, val + n_N, val + n_O, val = 14 Calculate the number of electrons needed to completely fill the valence shells for hydrogen (n_H, full = 2), nitrogen (n_N, full = 8), and oxygen (n_O, full = 8): 3 n_H, full + n_N, full + n_O, full = 22 Subtracting these two numbers shows that 22 - 14 = 8 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 4 bonds and hence 8 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 14 - 8 = 6 electrons left to draw: Answer: | |](../image_source/80c69094ba1fa9de6093cd0b144ec090.png)
