Question

Carbon has four valence electrons, and oxygen has six valence electrons. If carbon and oxygen bond covalently, which of the following is the correct Lewis dot (electron dot) structure for carbon dioxide?

Answer 1

A Lewis dot structure with the following configuration: one oxygen atom with six valence electrons, a double bond to a carbon atom, followed by a double bond to a second oxygen atom which has six valence electrons. It would have smaller atomic radii than Si and higher ionization energies than Si.

Answer 2

the correct answer is 4  hope this helps
