the polar molecule has a higher boiling point
Oxygen, hydrogen, nitrogen, chlorine, fluorine have diatomic molecules.
Molecular orbital theory predicts that ground state diatomic oxygen has two unpaired electrons (it is a diradical) which occupy its pi orbitals. These unpaired electrons produce a magnetic moment and are responsible for the paramagnetic property of diatomic oxygen.
Potassium fluoride (KF) is not a diatomic molecule because it consists of an ionic bond between potassium (K) and fluoride (F) ions. In an ionic bond, the atoms do not share electrons to form covalent bonds, as is the case in diatomic molecules like O2 or N2.
Oxygen and hydrogen have diatomic molecules.
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.
The bonds in diatomic molecules are generally covalent. Covalent bonds involve the sharing of electrons between atoms, whereas ionic bonds involve the transfer of electrons from one atom to another. Diatomic molecules, such as O2 and N2, share electrons to form stable molecular structures.
The main difference is in the number of electrons shared in the bond. Diatomic chlorine (Cl2) forms a single covalent bond, sharing 1 pair of electrons, while diatomic oxygen (O2) forms a double covalent bond, sharing 2 pairs of electrons. This difference affects the bond strength and characteristics of the molecules.
Bohr diagrams represent the electron shells of individual atoms, so they are not typically used for diatomic molecules, which involve two atoms sharing electrons to form a bond. Lewis structures or molecular orbital diagrams are more commonly used to represent the electron distribution in diatomic molecules.
The valence electrons
Hydrogen, in its elemental form, forms diatomic molecules, H2 , so it can be considered molecular.

Diatomic molecules. Halogens in particular.
Elements like chlorine form diatomic molecules because they are more stable in their molecular form rather than as individual atoms. By sharing electrons and forming a covalent bond with another atom of the same element, they achieve a more stable electron configuration. This stability helps lower their overall energy, making diatomic molecules the preferred state for certain elements.
H (hydrogen) exits as diatomic molecules
Several chemical elements have diatomic molecules: halogens, hydrogen, oxygen, nitrogen.
