chemical diagram

Build a chemistry structure by placing atoms, bonds, charges, and electrons.

Build the Lewis diagram for carbon dioxide, $\mathrm{CO_2}$ .

Atoms

Drag an atom onto the canvas, or tap an atom and then tap where you want it.

Bonds

Solution

Carbon is central in $\mathrm{CO_2}$ . Each oxygen forms a double bond to carbon and has two lone pairs, so each atom has an octet and the formal charges are zero.
