"-2" is the electric charge of the oxygen ion among the following choices given in the question. It actually needs two electrons to complete the stable outer shell. The correct option among all the options that are given in the question is the third option or option "C". I hope that the answer has helped you.
Answer:
Molecules/State
Explanation:
We know from the kinetic molecular theory that matter is made up of molecules. These molecules are in constant motion at various velocities and energies.
The total thermal energy refers to the total kinetic energies of these particles. It depends on the temperature of the system, the energies of the molecules present in the material and the arrangement of the object's molecules (states of matter).
Two oxygen atoms in a oxygen molecule share two electrons<span>. Oxygen atoms only have 6 </span>valence electrons<span> (</span>electrons<span> in the outer shell). They want 8 </span>electrons<span> so they need to steal two or share two.</span>
Carbon has a tendency to form covalent bonds.
