Identify the following reactions as either oxidation or reduction :
`K - e^(-) to K^(+)`

Explanation

To identify the reaction `K - e^(-) to K^(+)` as either oxidation or reduction, we can follow these steps:

### Step 1: Identify the initial and final states of the element.
- The initial state of potassium (K) is in its elemental form, which has an oxidation state of 0.
- The final state of potassium is `K^(+)`, which has an oxidation state of +1.

### Step 2: Determine the change in oxidation state.
- The oxidation state changes from 0 (in elemental potassium) to +1 (in `K^(+)`).
