State the product formed and write the balanced equation to show the reaction between hydrogen and sodium metal.

Explanation

To determine the product formed when hydrogen reacts with sodium metal, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are hydrogen (H₂) and sodium metal (Na).

### Step 2: Understand the Reaction
When sodium (Na) reacts with hydrogen (H₂), sodium donates one electron to hydrogen. Sodium has one electron in its outer shell (atomic configuration: 2, 8, 1) and can easily lose this electron. Hydrogen, on the other hand, needs one electron to complete its outer shell (which can hold a maximum of 2 electrons).
