Question

Sodium forms na+ not na+2 why

Answer 1

Answer:

Explanation: because the sodium have a one positive ion and valence of sodium is one so the sodium ( Na) have form 1 not na2

Answer 2

the atomic number of sodium is 11...

the electronic configuration of sodium is 1s² 2s² 2p⁶ 3s¹....when one electron is removed from its outer most shell ...the atom becomes stable...but if we try to remove 2nd valence electron i.e Na+2 it becomes less stable than Na+ ...(according to half filled and full filled stability )... and also the ionization enthalpy of 2nd valence electron is very high than 1st valence electron..

Therefore Na+ is more stable than Na+2
