# Molecule with 13 total electrons

Is there a stable molecule with total number of electrons equal to 13? Molecule can be either organic or inorganic

• Aluminium metal? atomic number 13... – user4076 Feb 19 '14 at 6:32
• Apart from $\ce{Al}$ I am not sure whether they exist. You're pretty much always going to need period 2 atoms for this number of electrons and all the molecules I can dream up have an even number of electrons. Maybe someone more experienced in organic synthesis/plenty of knowledge on molecular bonds can explain why (if) this is the case?! – Michiel Feb 19 '14 at 6:42
• Nitric oxide NO is stable radical, but sadly, with 15 electrons. – ssavec Feb 19 '14 at 9:49

There are quite some molecules that are persistent (= live long enough in solution to allow for a spectroscopical characterization, but cannot be isolated) or even stable (= can be isolated, bottled and/or used as a starting material) that have an odd number n of electrons, however $n \ne 13$.
