# What is the oxidation number for potassium?

Jan 1, 2017

For potassium metal..............?

#### Explanation:

The metal has neither accepted nor donated electrons. The element is zerovalent.

Most of the time, the metal acts as a one electron reductant:

$K \left(s\right) \rightarrow {K}^{+} + {e}^{-}$

And thus in its compounds, the oxidation state of potassium is almost invariably $+ I$. Look at examples, $K C l$, $K {O}^{t} B u , {K}_{2} C {O}_{3} , K O H$.
