Draw the Lewis structure of beryllium oxide. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the beryllium (n_Be, val = 2) and oxygen (n_O, val = 6) atoms: n_Be, val + n_O, val = 8 Calculate the number of electrons needed to completely fill the valence shells for beryllium (n_Be, full = 4) and oxygen (n_O, full = 8): n_Be, full + n_O, full = 12 Subtracting these two numbers shows that 12 - 8 = 4 bonding electrons are needed. Each bond has two electrons, so in addition to the 1 bond already present in the diagram add 1 bond. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 1 bond by pairing electrons between adjacent highlighted atoms: Answer: | |
