The CsFr molecule is predicted to have francium at the negative end of the dipole, unlike all known heterodiatomic alkali metal molecules. Francium superoxide (FrO 2) is expected to have a more covalent character than its lighter congeners; this is attributed to the 6p electrons in francium being more involved in the francium–oxygen bonding.

Francium-223 is the most stable isotope, with a half-life of 21.8 minutes, [8] and it is highly unlikely that an isotope of francium with a longer half-life will ever be discovered or synthesized. [22] Francium-223 is a fifth product of the uranium-235 decay series as a daughter isotope of actinium-227; thorium-227 is the more common daughter. [23]

Sodium nitride and potassium nitride has been generated, but remains a laboratory curiosity. The nitrides of the alkaline earth metals that have the formula M 3 N 2 are however numerous. Examples include beryllium nitride (Be 3 N 2), magnesium nitride (Mg 3 N 2), calcium nitride (Ca 3 N 2), and strontium nitride (Sr 3 N 2). The nitrides of ...

In chemistry, a hydridonitride (nitridohydride, nitride hydride, or hydride nitride) is a chemical compound that contains both hydride (H −) and nitride (N 3−) ions.These inorganic compounds are distinct from inorganic amides and imides as the hydrogen does not share a bond with nitrogen, and usually contain a larger proportion of metals.
Magnesium nitride, which possesses the chemical formula Mg 3 N 2, is an inorganic compound of magnesium and nitrogen. At room temperature and pressure it is a greenish yellow powder. At room temperature and pressure it is a greenish yellow powder.
Arsenide nitrides or nitride arsenides are compounds containing anions composed of nitride (N 3−) and arsenide (As 3−). They can be considered as mixed anion compounds or mixed pnictide compounds. Related compounds include the arsenide phosphides, germanide arsenides, arsenide carbides, and phosphide nitrides.
