Magnesium burns with a _____ flame.

Explanation

To answer the question "Magnesium burns with a _____ flame," we can follow these steps:

### Step 1: Identify the Element
We are focusing on magnesium, which is an alkaline earth metal found in Group 2 of the periodic table.

**Hint:** Think about the properties of metals when they react with oxygen.

### Step 2: Understand the Reaction
When magnesium burns, it reacts with oxygen in the air. The chemical reaction can be represented as:
\[ 2 \text{Mg} + \text{O}_2 \rightarrow 2 \text{MgO} \]
This shows that magnesium combines with oxygen to form magnesium oxide.

**Hint:** Consider what happens when metals react with oxygen; they often form oxides.

### Step 3: Observe the Flame Color
During the reaction, magnesium burns brightly and produces a specific color of flame. In this case, magnesium produces a dazzling white flame.

**Hint:** Recall the colors associated with different elements when they burn.

### Step 4: Conclude the Answer
Based on the reaction and the observation of the flame color, we conclude that magnesium burns with a **white dazzling flame**.

**Final Answer:** Magnesium burns with a **white dazzling flame**.
