Lewis structure
![Draw the Lewis structure of hydrogen selenide. Start by drawing the overall structure of the molecule: Count the total valence electrons of the hydrogen (n_H, val = 1) and selenium (n_Se, val = 6) atoms: 2 n_H, val + n_Se, val = 8 Calculate the number of electrons needed to completely fill the valence shells for hydrogen (n_H, full = 2) and selenium (n_Se, full = 8): 2 n_H, full + n_Se, full = 12 Subtracting these two numbers shows that 12 - 8 = 4 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 2 bonds and hence 4 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 8 - 4 = 4 electrons left to draw: Answer: | |](../image_source/f000e6b3a107d9a4173a1677cdae7104.png)
