The bronze coloured solution is diamagnetic or paramagnetic?

Explanation

To determine whether a bronze-colored solution is diamagnetic or paramagnetic, we can follow these steps:

### Step 1: Understand the Formation of the Bronze-Colored Solution
The bronze-colored solution is formed when an alkali metal (represented as M) reacts with liquid ammonia or diluted liquid ammonia. This reaction results in the formation of an ammoniated cation (MNH3X) and the release of an electron.

**Hint:** Consider the role of alkali metals and their reactions with ammonia.

### Step 2: Identify the Color Change
