Answer:
in the diagram shown, Oxygen is the only one that has a double bond.
Step-by-step explanation:
Chemical bonds are the way that electors are shared between atoms to form molecules whose energy is less than the energy of individual atoms.
A graphical way to show these electrons is to represent them by point in the atoms. Every other point represents a shared bond or pair of electrons.
Therefore for simple bonds two electrons are drawn. For double bonds four electrons and for triple bonds six electrons.
Therefore, in the diagram shown, Oxygen is the only one that has a double bond.
