Complete the following equations and state whether they are oxidation or reduction reaction.
`Na^(+)+____toNa`

Explanation

To complete the equation and determine whether it is an oxidation or reduction reaction, follow these steps:

### Step 1: Identify the missing component
The given equation is:
\[ \text{Na}^+ + \_\_ \rightarrow \text{Na} \]

To complete this equation, we need to identify what is required for sodium ion (\( \text{Na}^+ \)) to become sodium metal (\( \text{Na} \)). Sodium ion has a positive charge and needs to gain an electron to become neutral sodium.
