# Where does the extra electron come from in the Lewis dot structure of OH-? [duplicate]

Hydrogen has one valence electron and oxygen has 6 valence electrons. However, the dot structure shows 3 lone pairs of oxygen and 1 shares with hydrogen.How is that possible?

• The extra electron comes from that "-" in "OH-". If we just took two neutral atoms, O and H, they wouldn't form $\ce{OH-}$, but a neutral particle instead. – Ivan Neretin Aug 10 '16 at 6:16
• @Mithoron However, the answer to the question you refer does not answer my question nor the question you refer. The answer just mentions the algorithm of Lewis dot structure. And that is not my doubt. Reliable theory needs reliable observations. – Mathivanan Palraj Aug 11 '16 at 0:36
