here is the next video related to carbon dioxide structure that is a step by step guide to draw lewis structure of co2.
all the steps are same that we already describe in the previous videos like, Arrange the symbols of the elements of the compound as you would
expect the atoms to be arranged in the compound. The element with the
highest bonding capacity is generally written in the central position.
2. Add up the number of valence electrons available in each of the atoms
. If the structure is a polyatomic ion, add one electron for
each unit of negative charge, or subtract one for each unit of positive
charge.
3. Place one pair of electrons between each adjacent pair of elements
(forming single covalent bonds) .
4. Place pairs of the remaining valence electrons as lone pairs on the peripheral atoms (not the central atom) .
5. If octets are not complete, move lone pairs into bonding position between
those atoms and the central atom until all octets are complete
.
6. If the peripheral atoms all have complete octets and there are pairs of electrons remaining, place these electrons as lone pairs on the central atom.
7. Count the number of bonds between the central atom and the peripheral
atoms. If this number exceeds the bonding capacity of the central atom,
one or more of the bonds is coordinate covalent. To identify which ones,
try removing the peripheral atoms one at a time. If you can do this and
leave the central structure with complete octets, you have identified coordinate covalent bonds (.
8. To give the structural formula, remove the dots representing the lone pairs
and replace bond dots with dashes .
9. If you are representing a polyatomic ion, place brackets around the entire
structure and write the charge outside the brackets
