Two oxygen atoms form a stable molecule by sharing two pairs of electrons, forming a double covalent bond. This is an important process for achieving the required octet electron configuration for both oxygen atoms.
When two oxygen atoms combine to form a molecule, the type of bond they form is a double covalent bond. An atom of oxygen has six electrons in its valence shell and it requires two more to achieve stability, hence, the oxygen atom achieves this equilibrium by sharing two pairs of electrons forming a double covalent bond. This is similar to the example of hydrogens and an oxygen atom sharing electrons to form a water molecule, where covalent bonds are also present.
The creation of a double bond occurs as these atoms share more than one pair of electrons to attain the required octet configuration. This could also be seen in bonds formed between carbon and oxygen atoms in formaldehyde (CH₂O), or between carbon atoms in ethene (C₂H4).
The covalent bond formed between these two oxygen atoms is, therefore, a key component for them to form a stable molecule.

In wave mechanical model an orbital is defined as
Further explanation:
Bohr's model could not account for duality of matter and also contradicted the Heisenberg uncertainty principle. To overcome these weaknesses, a wave mechanical model was developed. The basis of this model was the Schrodinger wave equation of hydrogen atom.
The salient features of the wave mechanical or quantum mechanical model are as follows:
A. The energy associated with electrons present in atoms can take only certain discrete values. This is known as the quantization of energy.
B. Such quantized energy levels are a consequence of wave characteristics of electrons and allowed values are dictated in accordance with the solutions obtained from the Schrödinger wave equation.
C. The exact position as well the velocity of an electron cannot be precisely determined as it obeys the Heisenberg’s uncertainty principle. This leads to an important concept that path of an electron can never be precisely defined. Therefore it is better to use the term probability of locating electron.
D. The region of space around the atom in which the probability of locating any electron is highest is known as the orbital. The physical significance of the orbital is that it can be described using the values of . There are several possible values of . as can be obtained from the solving of Schrodinger equation. So there are several numbers of orbitals associated with an electron.
E. The utility of is that its square is directly proportional to the probability of locating an electron at a point within an atom. Hence the orbital is not a circular region of space but a region where the probability of locating an electron is highest.
Therefore, in the wave-mechanical model of the atom, a region of the most probable location is defined as orbital. Hence, the correct option is .
