Oxides and hydroxides

[Carlie_Dorostkar_1A]

Does anyone know what influences an element to form an oxide rather than a hydroxide?

[Chem_Mod]

We can define an oxide as a binary element with just one oxygen

Where a hydroxide is an oxide with an element and at least one hydrogen (water)

Metals typically form ionic oxides, and if there is enough presence of water or hydrogen a hydroxide may be formed. But it depends on the reaction conditions and the specific element.

From left to right on the periodic table, acid-base character of oxides and hydroxides go from basic to acidic.

Increasing charge on an anion increases the production of basic solutions.
As electronegativity increase, production of ionic cations increases because elements are more able to adopt a cation.
As ionization energy increases, the acidic nature increases.

Hope this helps! Feel free to follow up with more specific questions or an example
