In carbon dioxide (CO2), carbon and oxygen are attached to each other through a double bond. Oxygen requires 2 electrons to complete its valence shell, and carbon has 4 valence electrons. By forming a double bond, carbon shares 2 of its valence electrons with one oxygen atom. The structure of carbon dioxide can be represented as:
O=C=O
Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)(1 point)ResponsesC=O–OC=O–OO=C=OO=C=OO=C–OO=C–OC–O–O
