It doesn't. Oxygen must gain (or borrow) two electrons to complete its outer shell since it has only 6 electrons in its valence shell.
Oxygen is atomic #8 in the Periodic Table, meaning it has 8 electrons. The first shell of an element needs only 2 electrons to be stable and relatively unreactive. Shells (energy levels) beyond the first need 8 electrons to be stable, but oxygen has only 6 left because 2 were used in the first shell. Therefore, oxygen needs 2 more to complete its outer (valence) shell.
Oxygen achieves a full outer electron shell by gaining two electrons, which allows it to reach a stable electron configuration similar to noble gases. This stability is energetically favorable for oxygen as it reduces the overall energy of the atom. Additionally, gaining two electrons allows oxygen to form more stable compounds with other elements.

What does adding one 2s electron for Lithium do to the energy of the 2 p electrons Why does this make sense?
Lithium belongs to atomic number 3 adding 1 electron in the energy shell does not make sense because it will still be unstable.
Can graphite be used as an electron?
Question makes no sense, you might as well be asking "Can brick be used as water?".
What are the chief function of the respiratory system?
The chief function of the respiratory system is to facilitate the exchange of oxygen and carbon dioxide between the body and the environment. This is achieved through breathing, where oxygen is taken in and carbon dioxide is expelled. The respiratory system also helps regulate the body's pH balance and supports the sense of smell.
Does mold need oxygen to grow?
No, mold does not require oxygen to grow. Mold spores can thrive in environments with low oxygen levels.
Why does the structure H-C equals C-H fail to make sense chemically?
The structure H-C=C-H fails to make sense chemically because carbon needs to form four bonds to achieve a stable electron configuration. In this structure, carbon only has two bonds, which violates the octet rule. Carbon typically forms double bonds with oxygen and nitrogen, not with carbon.

Can an object gain 6.5 electrons?
In modern physics, particles can certainly have or be assigned a fractional charge (like quarks with a charge of +/- 2/3) or fractional spin (like the spin 1/2 fermions) but the concept of a fraction of a particle is not recognized. An object gaining six electrons is possible but gaining a half of an electron isn't meaningful. In an abstract sense, two atoms might share an electron in a bond (with covalent behavior) but in reality this would be more like a probability cloud with an electron sharing its "time" partly with one atom and partly with the other.

How did the narrator free by the end of the story?
The narrator in the story is freed by gaining a sense of self-awareness and understanding, usually by gaining perspective on their actions, emotions, or circumstances. This newfound understanding often leads to acceptance, growth, or reconciliation, ultimately providing the narrator with a sense of liberation or release.

What does adding one 2s electron for Lithium do to the energy of the 2 p electrons Why does this make sense?
Lithium belongs to atomic number 3 adding 1 electron in the energy shell does not make sense because it will still be unstable.
What did Erik Erikson think was the first psychosocial dilemma faced by a newborn?
He said it was gaining a sense of trust, instead of mistrust.
What are company goals?
Goals set by a company. Aimed usually to be achieved in a whole sense or by a certain time period.
By introducing wolves to Yellowstone have their goals been achieved?
In the sense that humans have PARTIALLY undone the horrible damage they did to the way that Yellowstone was intended to be at its creation, the successful re-introduction of wolves has been a goal achieved.
