# What is the difference between the hydroxides of non-metals, and the hydroxides of metals?

And a few oxo-acids are ${\left(H O\right)}_{2} S {\left(= O\right)}_{2}$, ${\left(H O\right)}_{3} P = O$, $H O \stackrel{+}{N} \left(= O\right) {O}^{-}$, and ${\left(O =\right)}_{3} C l O H$...what are the conventional names of these acids? On the other hand, when a less electron-rich metal forms an hydroxide, electron density is not polarized away from the $O - H$ bond...which remains intact, and, in solution gives ""^(-)OH ions...
