Question

chemical bonding draw an illustration that would demonstrate the covalent bonding between two oxygen atoms. then place an “x” on the graph below to determine the optimal bond length for these two atoms.

Explanation:

Step1: Draw covalent - bond illustration

Each oxygen atom has 6 valence electrons. To achieve an octet, two oxygen atoms share two pairs of electrons, forming a double - covalent bond. We can represent the oxygen atoms as O, and the shared electrons as lines between them: O=O.

Step2: Determine optimal bond length on graph

The optimal bond length corresponds to the minimum of the potential energy curve. On the given graph, the point R represents the minimum of the potential energy (U) curve. So, we place an "x" at point R on the graph.

Answer:

Draw O=O for the covalent - bond illustration and place an "x" at point R on the graph.
