A metal M is found in nature as `MCO_3` It is used in galvanising iron articles. Name the metal.

Explanation

To solve the question, we need to identify the metal M that is found in nature as MCO₃ and is used in galvanizing iron articles. Here’s the step-by-step solution:

### Step 1: Identify the Metal Carbonate
The question states that the metal M is found in nature as MCO₃. This indicates that M is a metal that forms a carbonate compound. Common metal carbonates include calcium carbonate (CaCO₃), magnesium carbonate (MgCO₃), and zinc carbonate (ZnCO₃).

**Hint:** Look for metals that are known to form carbonates.

### Step 2: Understand the Process of Galvanization
