Which is the correct Lewis structure for ?
Solution 10 SAQ Let’s try to solve for the letter b) Step 1 of 3 The formula CO make us note that one atom of Carbon is linked to 3 Oxygens, for this reason 3 we can even exclude the option d). Step 2 of 3 Since Carbon belongs to the group IV A, it has 4 electrons in the Valence shell. Oxygen, since it belongs to the group VI A, has six electrons, hence it must have six electrons surrounding it. Let’s try to write down one structure. If we calculate the formal charge of each atom, we could note that the atom of Oxygen bonded by a single link have a negative charge on each other, thus, we can represent the whole carbonate ion indicating the 2- charge out of the brackets, in the upper right corner.
