Silicon is the most abundant element on earth(T/F)

Explanation

To determine whether the statement "Silicon is the most abundant element on Earth" is true or false, we can follow these steps:

### Step 1: Identify the most abundant element on Earth
- The most abundant element on Earth is oxygen. It constitutes about 47% of the Earth's mass.

### Step 2: Identify the abundance of silicon
- Silicon is the second most abundant element on Earth, making up approximately 28% of the Earth's mass.

### Step 3: Compare the abundances
- Since oxygen is more abundant than silicon, we can conclude that silicon is not the most abundant element.

### Step 4: State the conclusion
- Therefore, the statement "Silicon is the most abundant element on Earth" is false.

### Final Answer
- **False**
