We draw a carbon atom and change it to oxygen First we draw a new C-C bond: Click the Sketch Atombutton and make sure C
is the selected element
Click on the carbon on the left of the double bond and sprout a bond. Click Esc to stop drawing.
Then click the selection tool and select the newly drawn carbon atom. Click the Modify Element button. You will find the possibility to select some elements straight away, but you also can choose the option Periodic Table.
We choose periodic table and click on the element symbol for oxygen and Ok. When you remove the highlight of the atom you previously marked by clicking somewhere in the 3D-atomistic document, you will find that the carbon atom was replaced by an oxygen atom.

A more reasonable geometry
The clean button give the molecule a reasonable geometry;
i.e. it corrects the angles, bond lengths, recognises that the saturated ring has a chair conformation
BUT it does not do a geometry optimisation!!
