Oxygen has a electron arrangement is 2,6 or 1s2 2s2 2p4
It is trying to achieve the electron arrangement of Neon, 2 8 (as all energy levels/orbitals are full)
So it will need to form two covalent bonds to get that, hence it will form a double covalent bond O=O
Fluorine has an electron arrangement of 2, 7 or 1s2 2s2 2p5
Again it is trying to achieve the electron arrangement of Neon, 2 8 (as all energy levels/orbitals are full)
So It needs to form only one covalent bond, hence F-F
So by process of elimination it must be nitrogen.
But lets look at its electron arrangement anyway
Nitrogen has the electron arrangement of 2,5 or 1s2 2s2 2p3
So it needs to form 3 covalent bonds to achieve a stable electron arrangement.

N
This triple bond is very strong, so strong in fact that very few things can break it! Lightning is one of them. This is why the majority of the earth atmoshpere is make of Nitrogen - because it sits there not reacting with anything!
Elements such as hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) can form diatomic molecules joined by single covalent bonds. For example, H2, N2, O2, F2, Cl2, Br2, and I2.
The halogens (Group 17) are the family of elements that most often exist as diatomic molecules in their elemental form. This includes elements like chlorine (Cl2), fluorine (F2), bromine (Br2), and iodine (I2).
Fluorine, Chlorine, Bromine, Iodine, Oxygen, Nitrogen and Hydrogen all exist as diatomic molecules.
Diatomic homonuclear molecules are hydrogen H2, oxygen O2, nitrogen N2, fluorine F2, chlorine Cl2, bromine Br2, iodine I2 and (theoretically) astatine At2. Diatomic heteronuclear molecules encompass a broader range of compounds such as carbon monoxide CO, hydrogen chloride HCl, lithium iodide LiI, cyanide CN and calcium oxide CaO.
There are actually seven elements that fit that description - hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
All of the elements hydrogen, fluorine, chlorine, bromine, and iodine have this property.

Oxygen, hydrogen, nitrogen, chlorine, fluorine have diatomic molecules.
If you mean F2 (fluorine), it is a diatomic molecule of the element fluorine. It's the common form of pure fluorine, since the halogen elements are all diatomic molecules.
The halogens (Group 17) are the family of elements that most often exist as diatomic molecules in their elemental form. This includes elements like chlorine (Cl2), fluorine (F2), bromine (Br2), and iodine (I2).
Fluorine, Chlorine, Bromine, Iodine, Oxygen, Nitrogen and Hydrogen all exist as diatomic molecules.
The 7 elements that readily form diatomic molecules are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and Iodine. Astatine might theoretically form diatomic molecules, but it is so rare and radioactive that it is hard to study.
The seven diatomic elements are: Hydrogen Nitrogen Oxygen Fluorine Chlorine Iodine Bromine They are nonmetals.
H2, N2, O2, F2, Cl2, Br2, and I2 are all diatomic elements.
In the gaseous state, diatomic covalent molecules consist of two atoms bonded together by shared pairs of electrons. Common examples include hydrogen (H₂), oxygen (O₂), nitrogen (N₂), and fluorine (F₂). These molecules exist as gases at room temperature and pressure due to their relatively low molecular weights and the nonpolar nature of the covalent bonds. The diatomic form allows these elements to achieve stability through electron sharing, following the octet rule.
Oxygen, hydrogen, nitrogen, chlorine, and fluorine all form diatomic molecules.
The fact that hydrogen forms diatomic molecules makes it similar to the halogen family, which also consists of elements that typically exist as diatomic molecules in their natural state, such as chlorine and fluorine.
